Using words to write short numbers makes your writing look clean and classy. In handwriting, words are easy to read and hard to mistake for each other. While you may not need to write longer numbers as words that much, it’s still helpful practice. This wikiHow will explain how you can write numbers as words.
-
1
Learn to write numbers from 1 to 9. This is where it all starts. Learn these, and the rest gets much easier:
- 1 = one
- 2 = two
- 3 = three
- 4 = four
- 5 = five
- 6 = six
- 7 = seven
- 8 = eight
- 9 = nine
-
2
Write numbers from 10 to 19. Do you see how many of them look just like the numbers above, plus «teen» at the end? «Sixteen» (16) just means «six and ten» (6 + 10).
- 10 = ten
- 11 = eleven
- 12 = twelve
- 13 = thirteen
- 14 = fourteen
- 15 = fifteen
- 16 = sixteen
- 17 = seventeen
- 18 = eighteen
- 19 = nineteen

Count in tens from 20 to 90. Here’s how to write 20, 30, 40, and so on all the way to 100. You can recognize these numbers because they end in «ty» except 100).
- 20 = twenty
- 30 = thirty
- 40 = forty
- 50 = fifty
- 60 = sixty
- 70 = seventy
- 80 = eighty
- 90 = ninety
-
4
Combine words to write more numbers. Now you can write any number from 1 to 100. Let’s see how it works for the number 42:
- 42 is written with two numbers: 4 2.
- 2 is in the ones place, so this just equals 2. Write this as two.
- 4 is in the tens place, so this is actually 40. Write this as forty.
- Write the two parts together: forty-two. Don’t forget the — sign between them.
-
5
Count by hundreds. This part’s easy if you remember the basics. Just write the number as usual and add «hundred:»
- 100 = one hundred
- 200 = two hundred
- 300 = three hundred (and so on)
-
6
Write any number from 100 to 999. Just write the hundreds place, then the rest of the number. You don’t need to write «and» or anything else between them. Here are some examples:
- 120 = one hundred twenty
- 405 = four hundred five
- 556 = five hundred fifty-six
- 999 = nine hundred ninety-nine
-
7
Test yourself. Try writing a few numbers as words. Work on these, then highlight the space after the = sign to see if you’re right:
- 21 = twenty-one
- 37 = thirty-seven
- 49 = forty-nine
- 255 = two hundred fifty-five
- 876 = eight hundred seventy-six

Understand place values. We can tell what each digit in a number means based on where it is. Here’s what the first 9 place values are called:[1]
- 1 → the ones place.
- 10 → the tens place.
- 100 → the hundreds place.
- 1,000 → the thousands place.
- 10,000 → the ten thousands place.
- 100,000 → the hundred thousands place.
- 1000,000 → the millions place.
- 10,000,000 → the ten millions place.
- 100,000,000 → the hundred millions place.
-
2
Add commas to long numbers. Start from the right side of the number, at the ones place. Count three digits to the left, then add a comma. Keep separating the number in groups of three.
- For example, turn 458735 into 458,735.
- Write 1510800 as 1,510,800.
- You can use a period instead if that’s how people in your country write numbers.
-
3
Write the last two digits. Look at the two digits at the end of the number. This part is just like writing a normal two-digit number.
- 5,467,350 looks hard, but don’t worry. Start with just the 50 at the end. Write this as fifty.
-
4
Write the hundreds place. The next digit is the hundreds place. This is an easy one. Just write the number in that place, then add the word «hundred.» Write this in front of your number.
- In 5,467,350, the 3 is the hundreds place. Write this as ‘three hundred.
- Now we have ‘three hundred fifty.
-
5
Look at the next chunk of three. You just wrote the hundreds, tens, and ones place. The next three numbers are the thousands «chunk.» These are the hundred thousands, ten thousands, and one thousands. Write these the same way, then add the word «thousand.»
- In 5,467,350, the 467 is the thousands chunk.
- Write the 4 as four hundred.
- Write the 67 as sixty-seven.
- Write the whole chunk as four hundred sixty-seven thousand.
- Now we have four hundred sixty-seven thousand, three hundred fifty.
-
6
Do the same for the millions. The next chunk of three numbers are the millions. These are the hundred millions, ten millions, and one millions. This is just the same as before, but with millions at the end.
- In 5,467,350, we only have a 5 in the millions place.
- Write this as five million.
- Finish writing the number: five million, four hundred sixty-seven thousand, three hundred fifty.

Whether in French, English or any other language, you will need to know the rules for spelling and writing numbers in words. It is an essential element for any language: to tell the time, to ask for the price of something, to measure a distance or a quantity, etc.
In this article (mainly for beginners), I will show you how do you spell numbers in words and all the necessary number writing rules to avoid any mistakes.
👉👉 Don’t forget to take the Quiz at the end to test your understanding!
When should we consider writing numbers in words?
When it comes to spelling out numbers, you will find that most of the writing rules are not standard! And it’s quite painful! Do you have to write them in words or leave them as digits and numbers?
Writing numbers from zero to one hundred in non-technical handwriting is generally preferable. However, in scientific and technical writing, the most common style is to write numbers less than ten.
While we have exceptions to these rules, your major focus should be on consistently expressing numbers.
Also, you will need to consider the potential differences between various style guides (for instance, Chicago, APA, and MLA) to write numbers in correct form. Because these guides often describe different rules for using numbers in writing.
What is the difference between Digits, Numbers and Numerals?
Don’t confuse numbers with numerals and digits: it’s not the same thing!
In everyday language, it is very common to get confused. These three terms are indeed closely linked. Mathematically, however, these words do not have the same meaning.
What is a digit?
Digits are basic mathematical symbols with which a numerical value is associated. In the Arabic numbers symbolism used in the USA, there are only ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
- A digit is a single symbol used to write numbers.
What is a number?
A number represents a quantity, a value, a size. It can be composed of one or more digits.
- So the number is an idea, the numeral is how we write it.
For example :
- 875 is a number composed of the digits 8, 7 and 5.
- 7972410 is a number composed of 7 digits.
What is a numeral?
A numeral, which is one or more digits, is an ordered element in a series composed of several numbers.
For example, a room number, a telephone number, social security number…
π (Pi) is also a special number, although we can’t write it exactly, but we know the idea behind it!
How do you spell single-digit numbers ? (1 through 9)
Spell out the numbers between one and nine. Except if you run out of space, this is the most common way to write a one-digit number. Also write “zero”, as it can be easily confused with the letter “O”.
0 | Zero |
1 | One |
2 | Two |
3 | Three |
4 | Four |
5 | Five |
6 | Six |
7 | Seven |
8 | Eight |
9 | Nine |
Writing Double-Digit numbers from 10 to 90
10 | Ten |
11 | Eleven |
12 | Twelve |
13 | Thirteen |
14 | Fourteen |
15 | Fifteen |
16 | Sixteen |
17 | Seventeen |
18 | Eighteen |
19 | Nineteen |
20 | Twenty |
Notice that the numbers from 13 (thirteen) to 19 (nineteen) always end in “-teen”. For this reason, people between the ages of thirteen and nineteen are called “teenagers” (teenagers).
If you know how to write numbers from 1 to 20, you have already done half the job because, after that, writing out numbers in English is very regular. Aalso don’t forget that we use the comma to separate the thousands and the point to separate the decimals, however, in other languages it is upside down.
To write a number in words, it’s really very basic. We take the number of tens and separate it from the numbers of the units by a dash “-“.
- 20 in words: Twenty
- 30 in words: Thirty
- 50 in words: Fifty
- 80 in words: Eighty
- 90 in words: Ninety
Examples With dashes :
- 99 in words, it is enough to add the figure “ninety” to “nine”, which gives “ninety-nine
- 25 in words, it is enough to add the figure “twenty” to “five”, which gives “twenty-five
- 21 in words, it is enough to add the figure “twenty” to “one”, which gives “twenty-one
Hundreds and thousands in English
Writing out numbers in words with hundreds in English is also easy. We take the number of hundreds, add “and” and put the number or the numbers that follows
- 100 in words : A hundred or one hundred
- 200 in words : Two hundred
- 900 in words : Nine hundred
- 990 in words : Nine hundred ninety
As for the hundreds, it is very simple to write the numbers from 2000 to 900 000 in words.
Example:
- 4000 in words: Four thousand
- 8000 in words: Eight thousand
- 20000 in words: Twenty thousand
- 90000 in words: Ninety thousand
How do you write large numbers?
Maybe you are asking : How do you read a 7 digit number? Or even larger numbers!
It is quite easy, and this is very essential for business English in particular. If you say “billion” when you mean “million”, it can be a very big mistake! This is something you need to learn if you want to enhance your conversational and writing skills!
-
- 1000000 in words is a million in English.
- 1000000000 in words : Billion which is the equivalent of a thousand million that spelt billion in english (one thousand million)
In this video tutorial you will learn how to write large numbers in English step by step :
Writing Rule when beginning a sentence with a number
This is a rule that you can always use: Numbers at the beginning of a sentence are always spelled out, no matter how big they are.
Some times, it will look awkward to star a sentence with a figure. So in this case, you should reword it to avoid this.
What are the rules for hyphens?
You should always hyphenate numbers when writing a compound number between 21 and 99.
Any number that consists of two words is considered a compound number. For example, Sixty-seven, Seventy-seven, Twenty-one…
- Exception to this rule: 30, 40, 50, 60, 70, 80 and 90
- Numbers greater than 99 do not require a dash.
Rules for using commas and dots to separate numbers
In English writing, we split numbers greater than 999 with commas to make them easier to read.
We put a comma every third digit from the right, this is known as a “thousands-separator”. The decimal point is shown with a period or full stop.
Do not include spaces on either side of this comma.
- Example: Over 70,000 cars are manufactured every year
Separate thousands and millions in compound numbers using commas.
- Example: 1,681,860
Use no commas in decimals.
- Example: $7.52
If the date is given as month, day, year, use a comma before the year.
- Example: July 22, 2021
Numbers that are not money amounts, like serial numbers, years, and phone numbers are generally represented without commas.
In some countries, large numbers are separated by dots and the comma is used for decimals.
- Example: 211,357.59
How do you write money amounts?
Here are some basic guidelines for writing U.S. currency and money amounts in general usage.
For amounts less than $1, use numerals with the word cent or cents.
- Example: Gasoline dropped 8 cents per gallon.
If the reference comes next to another dollar amount of $1 or more, in this case the cents must be formatted with $ and numbers.
- Example: Prices will soon be increased from $0.47 to $1.33 per piece.
When writing money amounts between 99¢ and $1 Million, use the dollar sign and numerals.
- Example: The subscription service is $783.88 per month.
If you are writing a check, you have to spell out in words the dollar value and you can write the cents numerically.
Replace a decimal point with ‘and’ when you write out amounts on a check.
- Example: forty-six thousand Seven dollars and 33 cents
Rules for writing times
Use numerals when you need to write the exact time and when using a.m. and p.m. However, the time is spelled out when it is followed by o’clock.
Examples:
- He arrived at home at seven o’clock in the morning.
- Wake me up at 9:00 a.m.
Common Mistakes In Writing English Numbers
Mistake 1 : Large Numbers
The first mistake we’re going to look at is related to large numbers.
Don’t worry It’s so easy, just keep in mind, if you have a number or a specific amount of money before : hundreds, thousands, millions, billions, trillions. Make sure you don’t add an ‘S’ at the end.
Example:
- He is making millions of dollars online.
- He is making hundreds of dollars online.
So, notice there’s no specific number here, it’s just hundreds of dollars in general. We don’t know how many hundreds, but we just know somewhere in the hundreds. Same with millions, we don’t know how many millions, we just know he stole millions of dollars not a specific amount.
But, if you have a specific number, there shouldn’t be an ‘S’, even though there’s more than one.
Example:
- I have 9 hundred followers.
- I have three thousand followers.
Mistake 2 : Single Numbers
The next mistake is very frequent. A lot of students and native English speakers get confused when they have to write numbers out.
If a number is a single number, or in other words, if you have a number where it’s just one word that you need to write (E.g. : Three, Twelve, Twenty…), in this case you will need to write it with letters.
Otherwise, if it’s not a single number (E.g. : Twenty-one, Two hundred eighty-four, one thousand six…), we wouldn’t write this out because it’s just too long. In this case we use the digits to write the numbers (E.g. : 21, 284, 1006,…)
Example:
- I have 7 cars. (wrong)
- I have seven cars. (correct)
The next thing you need to know is, when writing numbers at the beginning of a sentence you shouldn’t start with a numeral, the number should be written out in words.
Example:
- 7 birds are in the nest. (wrong)
- Seven birds are in the nest. (correct)
Useful Tip:
If you have a really long number to write, like in this sentence :
Three hundred eighty-six people attended the workshop.
It will be so long and awkward to write it. It’s better to change the sentence here.
So instead of saying Three hundred eighty-six people attended the workshop, you could say: The meeting was attended by 386 people
Mistake 3 : Adjectives
OK, so here is a final mistake that is seen often and that has to do with writing out numbers and also grammar in terms of pronunciation.
- The twenty-year-old boy.
- The boy is twenty years old.
If you’re using time, age or number of something as an adjective, use a hyphen and don’t add an “S”
Well, we have to think about whether or not we’re talking about an adjective. So in the first case, twenty-year-old boy is describing the noun boy, which is why we use hyphens here.
Mistake 4 : Writing money amounts
For figures followed by a dollar sign, don’t add the word “dollars”.
- Incorrect: I earned $2,344 dollars yesterday.
- Correct: I earned $2,344 yesterday.
Conclusion:
There are many different styles for writing numbers in word. This requires good grammar and focus on detail. Deciding whether to write numbers as words or as numerals is a matter of style. The key in all cases is to use a consistent style all along your writing.

Using words to write numbers when writing something in English makes your work look classy and clean. More importantly, it makes your writing readable and eliminates the hurdle of reading numbers and words together. In handwriting, words are not just easy to write but also difficult to mistake for each other. Even though longer numbers that have a lot of zeros at the end are not as useful as writing shorter numbers, it is still an important skill to learn for a student.
English is the most common, if not the universal, language used in institutes specifically for teaching purposes. Therefore, a student must learn how to convert numbers to words in English when writing something that involves the use of numbers. If you struggle to write numbers in words on a daily basis, then you may need to hire a private tutor online to help you out. In the beginning, roman numerals were used to represent mathematical numbers when writing, such as 1-I, 2-II, 3-III, and 4-IV, etc. However, now the preferred way of representing numbers is to write them in English words.
Before you learn how to spell numbers in words or you start using them in English, you must get familiar with the basics. The precondition to learning how to spell numbers in words is to know how to count to ninety-nine.
Counting From One to Ninety Nine
Let’s start with one to nine because that is where it all starts. These few numbers make up the whole empire of maths. So, it is important to know how to write them in English before you learn something else. Once, your grasp on them is strong, learning the rest of the numbers feels like a piece of cake:
Number | Word |
1 | One |
2 | Two |
3 | Three |
4 | Four |
5 | Five |
6 | Six |
7 | Seven |
8 | Eight |
9 | Nine |
Now that you know how to write the first nine numbers in words, for example, how do you write 1 or 7 in words, it is time for you to move on to learning how to write numbers from ten to nineteen.
The key to learning and remembering this set of numbers is to keep one simple observation in mind that most of the numbers (except ten, eleven, and twelve) are just their basic spelling (from one to nine) with the word “teen” at their end.
For instance, “Fourteen” (14) is just a combination of four and ten and means “four plus ten” (4 + 10). So, if you are worried about how to write 13 or 12 in words, this small and simple hack has got your back.
Moreover, learning all the words from one to twenty will enable you to spell higher numbers in words. Another reason to learn every number from one to twenty in English is that every number word’s spelling (from one to twenty) is different from other numbers.
Numbers | Words |
10 | Ten |
11 | Eleven |
12 | Twelve |
13 | Thirteen |
14 | Fourteen |
15 | Fifteen |
16 | Sixteen |
17 | Seventeen |
18 | Eighteen |
19 | Nineteen |
Once you know how to write from one to twenty in words, you can then proceed to learn about the rest of the numbers because your base is now strong. You can, at this point, learn to write any number you want in English whether it is how to write 50 in words, how to write 20 in words, or how to write 100.
The next step for you is to count from twenty to ninety in tens. Here is a demonstration of how to spell 20, 30, 40, 50, and so on all the way up to 100 in English.
One little hack for you here is that all these numbers, spelled in ten, end in the letters ‘ty’ except for 100.
Numbers | Words |
20 | Twenty |
30 | Thirty |
40 | Forty |
50 | Fifty |
60 | Sixty |
70 | Seventy |
80 | Eighty |
90 | Ninety |
Combining Words to Write More Numbers
You can write any number from one to hundred if your basics are strong. Let’s see an example of the number 56:
- 56 is written with two numbers: 5 and 6
- 6 is in the ones place and it is written as it is.
- 5 is in the tens place and so it is written as fifty.
- Write fifty and six together and add a hyphen between them.
- So, 56 = fifty-six
Then you have the hundreds which are easy to write if you remember the basic numbers and their spellings. All you need to do is add the word ‘hundred’ after each number.
Numbers (Hundreds) | Words |
100 | One Hundred |
200 | Two Hundred |
300 | Three Hundred |
400 | Four Hundred |
500 | Five Hundred |
600 | Six Hundred |
700 | Seven Hundred |
800 | Eight Hundred |
900 | Nine Hundred |
With the knowledge to write from one to hundred, any student can write any number higher than hundred. You just have to write the hundreds place, and then the rest of the numerical.
For example:
- 130 will be one hundred thirty
- 405 will be four hundred five
- 666 will be six hundred sixty-six
- 809 will be eight hundred eighty-nine
Writing Long Numbers
Before you start writing longer numbers, it is important for you to understand place values. Based on where a digit is situated in a number it can mean something different, so you can’t mess up the place of the digit if you want to get the number right. Here are the first nine place values:
Numbers | Place Values |
1 | the ones place |
10 | the tens place |
100 | the hundreds place |
1,000 | the thousands place |
10,000 | the ten thousands place |
100,000 | the hundred thousands place |
1,000,000 | the millions place |
10,000,000 | the ten millions place |
100,000,000 | the hundred millions place |
When writing higher numbers, you’ve to add commas. To add a comma, count three digits, starting from the right and add a comma. Repeat this to separate the number in groups of three.
For instance,
1200567 will be 1,200,567.
You can also add a period instead of a comma; if that is how the numbering system works where you live.
Writing Fractions in Words
If the denominator is the number 2, then such fractions are written as halves. So, 12is written as “one-half“, 23 is “two-halves“ and 192 is “nineteen-halves“, etc.
For the number 3 as denominator, the fractions are written as “third-thirds“. For 4, the fractions are “fourth/fourths“. And for 27, the fractions are “twenty-sevenths“, etc.
Writing Mixed Numbers in Words
Mixed numbers are numbers that have a whole number and a fraction together. Let’s look at an example to see how you can write a mixed number:
Consider 745 as the sample number. When writing it in words, it will be “seven and four-fifths“.
Conclusion
There you have it. A comprehensive guide to working out how to spell numbers in words. Follow our guide and you will become the best at writing numbers in words in your class.
Best of luck!

A concept regularly taught along with place value is “expanded form”, a way to write a number that displays each place separately. As we’ll see, there is considerable variation in terminology here, so parents may have to check what form a teacher wants, rather than look it up and expect a single answer!
Whole numbers
Here is a question from 1998:
Expanded and Standard FormsMy teacher has asked me to write numbers in standard form and expanded form. For example 4,017. What exactly does she want me to do?
Doctor Ameis replied:
Hello Mark, Expanded form is a way of writing numbers so that all that is hidden about them comes out into the open. The simplest way to write numbers in expanded form is to write them sort of in English. For 4,017, this becomes 4 thousands and 0 hundreds and 1 ten and 7 ones. This can be made to look like math by changing the words to math symbols.The expanded form for 4,017, then, is: 4 x 1000 + 0 x 100 + 1 x 10 + 7 x 1 The expanded form shows what each digit is worth (for example, the 4 is worth 4 x 1000, which is the same as 4 thousands, which equals 4000).
I love that initial description. We want to “expand” a number, sort of unfurling it, to show what is hidden in the compact form we call positional notation, making explicit what is implied by the position of each digit.
He says “sort of in English” because normal English would be “four thousand seventeen”, which is not so fully unfurled! We have to make it clear that 4 thousand means 4 times one thousand, and break up the clump that is “seventeen” as one ten and seven ones. So we have $$4017 = 4times 1000 + 0times 100 + 1times 10 + 7times 1$$ We’ll discuss below whether the zero should be included.
Here is another example. 12,345 becomes 1 ten thousand and 2 thousands and 3 hundreds and 4 tens and 5 ones. Changing the words to math symbols, 12,345 in expanded form is: 1 x 10,000 + 2 x 1,000 + 3 x 100 + 4 x 10 + 5 x 1
What is standard form? It’s just the form we started with, like Mark’s 4017. What if you’re given the expanded form first?
Standard form is the reverse of expanded form. You begin with expanded form and change it to the way we normally write numbers. For example, 3 x 1,000 + 5 x 100 + 7 x 10 + 4 x 1 can be changed to 3 thousands and 5 hundreds and 7 tens and 4 ones. This becomes: 3000 + 500 + 70 + 4 Do the addition and you get 3574 (the standard form).
Writing in standard form just means doing the arithmetic indicated by the expanded form. We’re putting the number back together again.
The intermediate form here, as we’ll see, is also sometimes called “expanded form”: $$3574 = 3000 + 500 + 70 + 4$$
But “standard form” doesn’t mean the same thing everywhere; in many countries that term refers to what we in America call “scientific notation”. As I have often commented, the least standardized word in all of math is the word “standard”.
In between: Short word form
A closely related question is represented by this from 2002:
Short Word FormHow is 474,136 written in short word form vs. standard form?
Doctor Sarah answered:
Hi Nicholas - thanks for writing to Dr. Math. The standard form of a number is written with commas separating every three digits. Your number 474,136 is already in standard form. In short word form, the number is written using a combination of numerals and letters. Your number would be 474 thousand 136
This form focuses on the “periods” (groups of three digits, separated by commas) in a number, which represent powers of 1000 (thousand, million, billion, …).
Another form (which one teacher who asked about it called “mixed form”) looks like “3 hundreds, 4 tens, 5 ones”, which is essentially the “sort of English” form of Doctor Ameis. A student once asked about “word-and-number” form, which might be what his teacher calls either of these.
In word form, the number is written in words: four hundred seventy-four thousand one hundred thirty-six
This could be called “long word form” or “standard word form”; it doesn’t directly relate to place value.
In expanded form or expanded notation, your number is written as: 4 x 100,000 + 7 x 10,000 + 4 x 1,000 + 1 x 100 + 3 x 10 + 6 x 1
This is the same expanded form we saw before. But we’ve seen teachers use that term for a couple variations.
Three kinds of “expanded”
A similar question (never archived) comes from 2009:
How do I write 680034987 in expanded notation?
Doctor Ian answered, taking a slightly different approach to the form:
Hi Monique, Suppose I want to write 4098 in expanded form. I can write it as a column addition, 4000 90 + 8 ----- 4098 If I write it on a single line, 4000 + 90 + 8 then it's in 'expanded form'.
This is the simplest “expanded form”; there are a couple others:
Note that this isn't really a mathematical thing. It's a math-teacher thing. So the 'right' answer will depend on what it is your teacher wants to see. Some teachers might require it to be written like 4*1000 + 9*10 + 8*1 and some might require it to be written as 4*10^3 + 9*10^1 + 8*10^0 It's really a matter of taste. Any one of those would be correct, but any teacher might decide to mark only one of them as 'right'. Anyway, do you see the main idea? Can you apply it to your number? Try that, and let me know what you come up with.
We’ve seen the first of these; the second we haven’t yet. This can be called exponential expanded form, or expanded form with powers of ten.
Incidentally, we have had a number of teachers or students ask us about the difference between “expanded form” and “expanded notation”, and it seems that some authors do distinguish these terms (e.g. here), saying that (400+90+8) is “expanded form” while (4times 1000+9times 10+8times 1) is “expanded notation”. But Common Core (here) calls the latter “expanded form”; and other sources (e.g. here) call the former “expanded notation”. I don’t think any of these naming conventions are standard. As Doctor Ian said, it’s just a matter of taste.
I’ll call the three forms “short expanded form“, $$498 = 4000+90+8$$
“long expanded form“, $$498 = 4times 1000 + 9times 10 + 8times 1$$
and “exponential expanded form“, $$498 = 4times 10^3 + 9times 10^1 + 8times 10^0$$
That’s just my choice of names, made up this minute!
Should you include zeros?
Here is a question (from 2012) that should have been archived, because it is surely a common issue:
How would you write a single digit number in expanded form? For example the number 6. We know that 16 is 10+6, but we are confused about the right way to do a single digit number. My teacher asks me to do 5 different things with the date everyday. Tally marks, money, place value blocks, odd/even, and expanded form. We are all confused about the right way to write single digit numbers in expanded form. I say it's just the number itself. My friend says you would do 0+6 like you do in money or time for single digit numbers. We really want to know what the right way to do it is.
Emily is right; but her friend isn’t terribly wrong. (Note that they are using “short expanded form”.) Doctor Ian answered:
Hi Emily, A single digit number is *already* expanded. You don't have to do anything. The problem with writing 0+6 is that you could also write 0+0+6, or 0+0+0+6, and so on. There would be no end to it. Just out of curiosity, if asked to write something like 1506 in expanded form, how would you do that?
If you require an added zero, how do you know when to stop? It seems best to stop before you start.
The new question is a good way to stimulate thought. We’ve already seen examples like this, probably chosen specifically to bring up this point.
Emily replied,
Thank you for helping us to understand math. Just to be sure I have this right, if the number is a single digit, I should just rewrite the number in the answer spot. Would it be better to leave it blank or to write, no expanded form? Emily
To answer your question 1506 in expanded form is 1000+500+6 right? I used to think I had to put a +0 in there where the tens go, but my teacher said that it wasn't needed.Well, now that brings up another question. What if the number is 40? 40 + 0?
Emily already has been told about zeros in the middle; but zeros on the left, and zeros on the right, seem different!
Doctor Ian responded first to the question about “no expanded form”:
Hi Emily, It would be better to just put the number there. For a single-digit number, the regular form and the expanded form are the same.
So there is an expanded form; it just isn’t different.
Next, about the zero in 1506 not being needed in expanded form:
I would agree.
The reason it’s needed in standard form is as a place-holder. In expanded form, places are explicit, so they don’t need to be “held”.
And then, on 40:
That *is* a good question. If we don't have to write the 0 for 1506, we probably wouldn't want to write it for 40, either. It might help to think about what 'expanded notation' is good for. For example, it's useful if we want to do 'lattice multiplication'. That is, if we want to multiply 234 by 56, we can make up a table: 50 6 200 30 4 We can multiply the individual parts, 50 6 200 10000 1200 30 1500 180 4 200 24 and then add those up to get the product: 234 * 56 = 10000 + 1500 + 200 + 1200 + 180 + 24 = 13104 Don't worry if you haven't learned about this yet. You will. But let's think about doing something like multiplying 40 by 56. The table would look like 50 6 40 2000 240 0 0 0 That last row isn't making much of a contribution, is it? So there's no real reason to include it. That's also why we wouldn't bother to write 1506 as 1000+500+0+6. Let's look at a table for that: 1000 500 0 6 30 30000 15000 0 180 9 9000 4500 0 54 Again, that third row isn't making much of a contribution. So there's no real reason to include it. This is the kind of thing that leads us to the decision not to include entries for places where the digit is zero. It just takes up space, without really being useful. Does this make sense?
A lot of math comes down to a question of what is useful.
Expanded form with decimals
A couple new issues arise when we include decimals, which are only mentioned in the archive in this question from 2001:
What is Expanded Notation?
We get more details in this unarchived question from 2010 explicitly about decimals:
My math assignment says I have to write expanded notation with numbers under 1, for example 0.05 and 0.7805
How do you do it? Especially the zero's. 0.00+ 0.05 0.000+ 0.7805Thanks Katie
The leading zeros might make a student trip up; it appears that Katie is trying to include terms for them, which would be confusing. I answered:
Weren't you given any examples in class? Or is this an assignment to test what you already know, and you have never been taught this before? I'd like to have seen some attempt (or an example of how you would write expanded notation for a number greater than 1) in order to give me a better idea where to start.
Students do sometimes ask questions about topics they missed, or on tests not associated with what they have already learned; it’s helpful when we can get such background information. Also, as we’ve seen, an example would clarify what kind of expanded form they are (or will be) learning. Lacking that information, I offered several options:
There are slightly different ways to write "expanded notation", but one form is to show the value of each digit in the number, like this: 123 = 100 + 20 + 3 or 123 = 1x100 + 2x10 + 3x1 That is, the 1 means 1 hundred, so we write either 100 or 1x100. The 2 means 2 tens, so we write 20 or 2x10; and the 3 means 3 ones, so we write 3 or 3x1.
These are my “short” and “long” extended forms, so far applied only to whole numbers. Now we extend the idea, using fractions:
The digit after the decimal point is the number of tenths, and the one after that is hundredths. So we would write 1.23 as 1.23 = 1 + 2/10 + 3/100 or 1.23 = 1x1 + 2x1/10 + 3x1/100 Does that remind you of something you've been taught? Can you tell whether one of these forms, or something like them, is the way you have been taught to write expanded form?
The short extended form is $$1.23 = 1times 1 + frac{2}{10} + frac{3}{100}$$ and the long extended form is $$1.23 = 1times 1 + 2timesfrac{1}{10} + 3timesfrac{1}{100}.$$
It looks like you may have been trying to write something like my first form, but using decimals rather than fractions: 1.23 = 1 + .2 + .03. That's a possible form, but I don't think it's very useful, and so I doubt it is what you would be expected to do. But you'd have to show me an example of what your teacher means by expanded notation in order for me to be sure.
I’m not sure whether anyone teaches this form, $$1.23 = 1times 1 + 2times .1 + 3times .01.$$
How many ways to name a number?
Occasionally, we got questions like this (unarchived) from 2007:
What are the five ways to name a number? e.g. 127
I have1. pictorial (drawing blocks)
2. words (one hundred twenty-seven)
3. expanded notation (100 + 2 10's + 7 1's) I suppose 127 is called standard notation. If so I have four of the five ways to name a number.
Doctor Rick answered:
Who says there are just five ways to name a number? That must be some educator's pronouncement, in which case you'll have to read the educator's book to get the full list. You can use scientific notation: 1.27*10^2. Or Roman numerals: CXXVII. Or hexadecimal: 7F. Or binary: 1111111. Or ancient Egyptian hieratic numerals. Or modern Arabic numerals. Or ancient Babylonian base-60 numerals. Or French words ... Honestly, I don't know what the answer is supposed to be.
Someone else asked about the four ways to name a number. I imagine each of these was really “the ___ ways we discussed in class”; such questions are particularly frustrating to parents when they don’t know what was taught, and assume it must be something universal.
Why so many ways to name a number?
Let’s look at one more unarchived question, this one from 2009:
Why are there so many forms or notations for numbers?Like Standard notation = 782
But there's also
Expanded notation = 782 = (7*100)+ (8*10)+(2*1)
Scientific notation = 1,000,000 = 10^6 (ten to the sixth power) * 1 = 1,000,000
Word form = seven hundred and eighty two
Word and Number form = (1,000) 1 thousandIt's just my teacher has taught us all these and I just find that there are A LOT.
Like here's an example of a question: "Write 107 in word form"
Answer: one hundred seven
We see here (long) expanded form, (long) word form, the “mixed” form I’ve mentioned, and also scientific notation, which uses a single power of ten. Doctor Ian answered:
I'll bet you have more than one pair of shoes, right? How come? Because different kinds of shoes are good for different situations, right? The shoes you wear to church aren't so good for the beach, and shoes for going out in the snow aren't so good for playing soccer, and so on. Each form for writing a number has its own uses, things it's good for. And it's not so good for other things!
This is the standard way to think about any such question. How about some specifics?
For example, we use word form when writing checks. If I wrote you a check for, say, 15.00 dollars, it would be easy for you to put some numbers in front of that when you go to cash it. You might change it to 915.00, for example. But if I write out 'fifteen and no/100', it's a lot harder to alter that. It's also useful for catching errors, e.g., some people write their sevens the way other people write their ones. So if you just see '15', that might mean fifteen, or it might mean seventy-five, depending on who wrote it. But if the words are written out, it's hard to confuse the two, isn't it?
These two reasons are fraud prevention (which was also one reason Europe held on to Roman numerals for so long!) and error detection (as when people write something like “two (2) copies”).
(We also use word form just to read numbers aloud, of course.)
Scientific notation makes really big numbers (like 602,000,000,000,000,000,000,000) or really small numbers (like 0.00000000056) easier to compare with other numbers, because we can just look at the exponents. It also makes them easier to work with, because we can manipulate the exponent and non-exponent parts independently. For example, to multiply 602,000,000,000,000,000,000,000 * 0.00000000056 --------------------------------- would be really hard to do, even with a calculator, without making a mistake of some kind. But if we write it as 6.02 * 10^23 * 5.6 * 10^-10 ----------------- we can just multiply 6.02 and 5.6, to get 33.7, and add the exponents, 6.02 * 10^23 * 5.6 * 10^-10 ----------------- 33.7 * 10^13 and adjust it back to scientific notation (i.e., so the first part is between 1 and 10), 6.02 * 10^23 * 5.6 * 10^-10 ----------------- 33.7 * 10^13 = 3.37 * 10^14 and it's pretty straightforward.
Each has its place.
Now, just as you don't want to wear your snow boots everywhere, using scientific notation is a bad idea for numbers that aren't very large, or very small! But for the right situation, it's a great tool to have. So basically, if mathematicians have invented a way of writing a number, it means that there is at least one situation where it solves a problem for them. Does this make sense?
Finally:
An exception is 'expanded notation'. This isn't used anywhere except in classrooms, as a way of teaching about place value. It's really not used outside of school.
And this is why the names and notations for expanded form(s) are not standardized: They are just teaching tools, not concepts mathematicians or scientists have to use (and therefore agree on).
Next time, we’ll look at some details of “word form”.
Number words are the alphabetical form of numbers. As the name suggests, these are numbers written in words. Word form is writing the numerical/number as you would say it in words.
‘Number words’ or ‘number names’ are simply the names assigned to numbers so that we can identify each number uniquely. When we talk about “math,” what is the first thing that comes to your mind? Numbers! Are you aware that numbers also have names called number names? Yes, like everything else in the world, numbers have names. Let us know the number name definition and the rules to write them.

Number Words: Definition
A number word or number name is a way to express numbers in their word form. We can express numbers using their number name form. The spelling of numbers in English is something we should focus on while writing the numbers in word form.
For example, we can write 1 as “one.” So, the number name for 1 is “one.”
Similarly, we can express the number 2 as “two” in its word form.
The number 3 as “three” in its word form, and so on.
For example:
With the help of the number words from one to ten, we can make number words of higher value.
It is important to learn every number word from One to Twenty to learn other number words. Also, the number words from eleven to twenty are very different from other number words.
After learning the number words up to twenty, it is important to learn the number words such as thirty, forty, fifty, sixty until hundred.
Once you know these number words, it is easy to make number words for higher value numbers.
For example:
The above two number words are made from learning the basic number words from one to ten, and the number words for tens value, like sixty, seventy and eighty.
As the numbers increase in value and become larger with three, four, five, six, seven and more digits, the names start to change.

Rules to Write Numbers in Word Form
While writing numbers in their number words form, we have to follow certain rules. These rules are as follows:
Rule 1
Always consider place values while writing numbers in the word form.
For example, the digit 2 at the ones place is read as 2. The same digit at the tens place has the value “twenty.” So, 22 can be written as “twenty-two.”
Rule 2
To write numbers between 1–20, refer to the number names chart.
To express numbers beyond 20 in words, you must follow a certain pattern. As per this pattern, the multiples of 10 up to 90 are written as thirty, forty, fifty, sixty, seventy, eighty, and ninety.
Rule 3
For writing multiples of 100 in word form, you can write the digit in the word form and add the word hundred after it.
For example, you can express 200 as two hundred in the word form, 600 as six hundred, and so on.
You can follow the same rule while writing multiples of 1000 in word form. The only difference is that you have to add the word thousand instead of hundred. For example, you can write 3000 as three thousand in the word form.
Rule 4
For writing two-digit or three-digit numbers in word form, you have to write them in their expanded form. Ensure that you take the position of 0 in account.
For example, you can write 107 (expanded into $100 + 0 + 7$) as one hundred seven.
The word form of 125 (expanded into $100 + 20 + 5$) is one hundred twenty-five.
Number Words or Number Names from 1 to 100
Here’s a table containing numbers 1 to 100 and their corresponding word forms:
The Number Words for Higher Values
It becomes easy to convert numbers to number words and number words to number if we know the number words.
For example:
Write the given numbers in words.
Write the given numbers in numerals.
Number Names as per the International Number System
In the international system, the numbers are organized into periods and groups. The periods are categorized as ones, thousands, millions, etc. Each period is grouped into three place values. While writing numbers in this system, we insert a comma or separator after every three digits from the right.
The place value names in the international system are as follows:
- Ones
- Tens
- Hundreds
- Thousands
- Ten Thousands
- Hundred Thousands
- Millions
- Ten Millions
- Hundred Millions
- Billions
- Ten Billions
- Hundred Billions
- Trillions, and so on
Example: Suppose you have to write the word form of the number 6,342,715 in the international system.
6,342,715 is Six Million Three Hundred Forty-two Thousand Seven Hundred Fifteen.
Place Value Chart for International System
Here is the place value chart for the international system:
From this place value chart, we understand:
- 1 million $= 1000$ thousand
- 1 billion $= 1000$ million
Tips and Tricks to Learn Numbers Names
Here are a few tips to help you learn and write numbers in their word forms:
- Write down 1 to 20 as numbers and their spellings.
- Write down the multiples of 10 up to 90 and their spellings.
For example, 10: Ten, 20: Twenty, 30: Thirty, and so on.
- Write down the multiples of 100 and their spellings.
For example, 100: Three hundred, 200: Two hundred, and so on.
- For two-digit numbers beyond 20, expand them and write them in words in their expanded form. For example, you can expand 32 as $30 + 2$ and write “thirty-two.”
- Follow the same technique for large numbers.
For example, you can expand 471 as “$400 + 70 + 1$” and write “four hundred seventy-one” or “four hundred and seventy-one.”
Number Names as per the Ordinal System
An ordinal number expresses the rank or position of something. That is why they are also known as ranking or positioning numbers.
Ordinal numbers are written as 1st, 2nd, 3rd, 4th, and so on.
Here is a chart of the first 50 ordinal numbers and their number names:
Fun Facts
- When writing ordinal numbers in their word form, we use the suffix -th for the numbers 11, 12, and 13; but for all other numbers ending with 1, 2, or 3, we use the suffixes -st, -nd, and -rd, respectively. For example, we express 51 as fifty-first, 52 as fifty-second, and 53 as fifty-third.
- The word form of the number 40 is forty and not fourty.
- When writing numbers between 21 and 99, we use a hyphen $(-)$ in between.
- To write number words, we can write the word form of the numbers as we say them.
Conclusion
Number names offer an easy way to identify and learn numbers. They can help us to understand how the number system functions. Knowing to read and write numbers in words can enable us to identify how numbers relate to one another.
Solved Examples
- Write the number 7575 in words.
Solution:
We can expand 7575 as $7000 + 500 + 70 + 5$.
7575 in word form is “seven thousand five hundred seventy-five.”
- What comes after the given number name: twenty-nine?
Solution:
Twenty-nine $= 29$
The number after 29 is $29 + 1 = 30$
30 in the word form is Thirty.
So, thirty comes after twenty-nine.
- Count the emojis in the given image and write the number in words.
Solution:
$5 + 4 + 3 + 2 + 1 = 15$
The given image has fifteen or 15 smileys.
- Express 2022 in words and also in the ordinal system.
Solution:
$2022 = 2000 + 0 + 20 + 2$
In words, we write it as “two thousand twenty-two.”
Also, 2022 is written as “two thousand twenty-second” in the ordinal system.
- Write the word form of 404.
Solution:
$404 = 400 + 0 + 4$
404 is four hundred four.
