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.

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.

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 1^st, 2^nd, 3^rd, 4^th, and so on.

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.

Источник

This article is about number words. For the mathematical notation of numbers, see numeral system.

In linguistics, a numeral in the broadest sense is a word or phrase that describes a numerical quantity. Some theories of grammar use the word «numeral» to refer to cardinal numbers that act as a determiner that specify the quantity of a noun, for example the «two» in «two hats». Some theories of grammar do not include determiners as a part of speech and consider «two» in this example to be an adjective. Some theories consider «numeral» to be a synonym for «number» and assign all numbers (including ordinal numbers like the compound word «seventy-fifth») to a part of speech called «numerals».^[1]^[2] Numerals in the broad sense can also be analyzed as a noun («three is a small number»), as a pronoun («the two went to town»), or for a small number of words as an adverb («I rode the slide twice»).

Numerals can express relationships like quantity (cardinal numbers), sequence (ordinal numbers), frequency (once, twice), and part (fraction).^[3]

Identifying numerals[edit]

Numerals may be attributive, as in two dogs, or pronominal, as in I saw two (of them).

Many words of different parts of speech indicate number or quantity. Such words are called quantifiers. Examples are words such as every, most, least, some, etc. Numerals are distinguished from other quantifiers by the fact that they designate a specific number.^[3] Examples are words such as five, ten, fifty, one hundred, etc. They may or may not be treated as a distinct part of speech; this may vary, not only with the language, but with the choice of word. For example, «dozen» serves the function of a noun, «first» serves the function of an adjective, and «twice» serves the function of an adverb. In Old Church Slavonic, the cardinal numbers 5 to 10 were feminine nouns; when quantifying a noun, that noun was declined in the genitive plural like other nouns that followed a noun of quantity (one would say the equivalent of «five of people»). In English grammar, the classification «numeral» (viewed as a part of speech) is reserved for those words which have distinct grammatical behavior: when a numeral modifies a noun, it may replace the article: the/some dogs played in the park → twelve dogs played in the park. (Note that *dozen dogs played in the park is not grammatical, so «dozen» is not a numeral in this sense.) English numerals indicate cardinal numbers. However, not all words for cardinal numbers are necessarily numerals. For example, million is grammatically a noun, and must be preceded by an article or numeral itself.

Numerals may be simple, such as ‘eleven’, or compound, such as ‘twenty-three’.

In linguistics, however, numerals are classified according to purpose: examples are ordinal numbers (first, second, third, etc.; from ‘third’ up, these are also used for fractions), multiplicative (adverbial) numbers (once, twice, and thrice), multipliers (single, double, and triple), and distributive numbers (singly, doubly, and triply). Georgian,^[4] Latin, and Romanian (see Romanian distributive numbers) have regular distributive numbers, such as Latin singuli «one-by-one», bini «in pairs, two-by-two», terni «three each», etc. In languages other than English, there may be other kinds of number words. For example, in Slavic languages there are collective numbers (monad, pair/dyad, triad) which describe sets, such as pair or dozen in English (see Russian numerals, Polish numerals).

Some languages have a very limited set of numerals, and in some cases they arguably do not have any numerals at all, but instead use more generic quantifiers, such as ‘pair’ or ‘many’. However, by now most such languages have borrowed the numeral system or part of the numeral system of a national or colonial language, though in a few cases (such as Guarani^[5]), a numeral system has been invented internally rather than borrowed. Other languages had an indigenous system but borrowed a second set of numerals anyway. An example is Japanese, which uses either native or Chinese-derived numerals depending on what is being counted.

In many languages, such as Chinese, numerals require the use of numeral classifiers. Many sign languages, such as ASL, incorporate numerals.

Larger numerals[edit]

English has derived numerals for multiples of its base (fifty, sixty, etc.), and some languages have simplex numerals for these, or even for numbers between the multiples of its base. Balinese, for example, currently has a decimal system, with words for 10, 100, and 1000, but has additional simplex numerals for 25 (with a second word for 25 only found in a compound for 75), 35, 45, 50, 150, 175, 200 (with a second found in a compound for 1200), 400, 900, and 1600. In Hindustani, the numerals between 10 and 100 have developed to the extent that they need to be learned independently.

In many languages, numerals up to the base are a distinct part of speech, while the words for powers of the base belong to one of the other word classes. In English, these higher words are hundred 10², thousand 10³, million 10⁶, and higher powers of a thousand (short scale) or of a million (long scale—see names of large numbers). These words cannot modify a noun without being preceded by an article or numeral (*hundred dogs played in the park), and so are nouns.

In East Asia, the higher units are hundred, thousand, myriad 10⁴, and powers of myriad. In the Indian subcontinent, they are hundred, thousand, lakh 10⁵, crore 10⁷, and so on. The Mesoamerican system, still used to some extent in Mayan languages, was based on powers of 20: bak’ 400 (20²), pik 8000 (20³), kalab 160,000 (20⁴), etc.

Fractional numerals[edit]

This is a table of English names for non-negative rational numbers less than or equal to 1. It also lists alternative names, but there is no widespread convention for the names of extremely small positive numbers.

Keep in mind that rational numbers like 0.12 can be represented in infinitely many ways, e.g. zero-point-one-two (0.12), twelve percent (12%), three twenty-fifths (3/25), nine seventy-fifths (9/75), six fiftieths (6/50), twelve hundredths (12/100), twenty-four two-hundredths (24/200), etc.

Other specific quantity terms[edit]

Various terms have arisen to describe commonly used measured quantities.

Unit: 1
Pair: 2 (the base of the binary numeral system)
Leash: 3 (the base of the trinary numeral system)
Dozen: 12 (the base of the duodecimal numeral system)
Baker’s dozen: 13
Score: 20 (the base of the vigesimal numeral system)
Shock: 60 (the base of the sexagesimal numeral system)^[9]
Gross: 144 (= 12²)
Great gross: 1728 (= 12³)

Basis of counting system[edit]

Not all peoples count, at least not verbally. Specifically, there is not much need for counting among hunter-gatherers who do not engage in commerce. Many languages around the world have no numerals above two to four (if they’re actually numerals at all, and not some other part of speech)—or at least did not before contact with the colonial societies—and speakers of these languages may have no tradition of using the numerals they did have for counting. Indeed, several languages from the Amazon have been independently reported to have no specific number words other than ‘one’. These include Nadëb, pre-contact Mocoví and Pilagá, Culina and pre-contact Jarawara, Jabutí, Canela-Krahô, Botocudo (Krenák), Chiquitano, the Campa languages, Arabela, and Achuar.^[10] Some languages of Australia, such as Warlpiri, do not have words for quantities above two,^[11]^[12]^[13] and neither did many Khoisan languages at the time of European contact. Such languages do not have a word class of ‘numeral’.

Most languages with both numerals and counting use base 8, 10, 12, or 20. Base 10 appears to come from counting one’s fingers, base 20 from the fingers and toes, base 8 from counting the spaces between the fingers (attested in California), and base 12 from counting the knuckles (3 each for the four fingers).^[14]

No base[edit]

Many languages of Melanesia have (or once had) counting systems based on parts of the body which do not have a numeric base; there are (or were) no numerals, but rather nouns for relevant parts of the body—or simply pointing to the relevant spots—were used for quantities. For example, 1–4 may be the fingers, 5 ‘thumb’, 6 ‘wrist’, 7 ‘elbow’, 8 ‘shoulder’, etc., across the body and down the other arm, so that the opposite little finger represents a number between 17 (Torres Islands) to 23 (Eleman). For numbers beyond this, the torso, legs and toes may be used, or one might count back up the other arm and back down the first, depending on the people.

2: binary[edit]

Binary systems are base 2, using zeros and ones. With only two symbols binary is used for things with coding like computers.

3: ternary[edit]

Base 3 counting has practical usage in some analog logic, in baseball scoring and in self–similar mathematical structures.

4: quaternary[edit]

Some Austronesian and Melanesian ethnic groups, some Sulawesi and some Papua New Guineans, count with the base number four, using the term asu or aso, the word for dog, as the ubiquitous village dog has four legs.^[15] This is argued by anthropologists to be also based on early humans noting the human and animal shared body feature of two arms and two legs as well as its ease in simple arithmetic and counting. As an example of the system’s ease a realistic scenario could include a farmer returning from the market with fifty asu heads of pig (200), less 30 asu (120) of pig bartered for 10 asu (40) of goats noting his new pig count total as twenty asu: 80 pigs remaining. The system has a correlation to the dozen counting system and is still in common use in these areas as a natural and easy method of simple arithmetic.^[15]^[16]

5: quinary[edit]

Quinary systems are based on the number 5. It is almost certain the quinary system developed from counting by fingers (five fingers per hand).^[17] An example are the Epi languages of Vanuatu, where 5 is luna ‘hand’, 10 lua-luna ‘two hand’, 15 tolu-luna ‘three hand’, etc. 11 is then lua-luna tai ‘two-hand one’, and 17 tolu-luna lua ‘three-hand two’.

5 is a common auxiliary base, or sub-base, where 6 is ‘five and one’, 7 ‘five and two’, etc. Aztec was a vigesimal (base-20) system with sub-base 5.

6: senary[edit]

The Morehead-Maro languages of Southern New Guinea are examples of the rare base 6 system with monomorphemic words running up to 6⁶. Examples are Kanum and Kómnzo. The Sko languages on the North Coast of New Guinea follow a base-24 system with a sub-base of 6.

7: septenary[edit]

Septenary systems are very rare, as few natural objects consistently have seven distinctive features. Traditionally, it occurs in week-related timing. It has been suggested that the Palikúr language has a base-seven system, but this is dubious.^[18]

8: octal[edit]

Octal counting systems are based on the number 8. Examples can be found in the Yuki language of California and in the Pamean languages of Mexico, because the Yuki and Pame keep count by using the four spaces between their fingers rather than the fingers themselves.^[19]

9: nonary[edit]

It has been suggested that Nenets has a base-nine system.^[18]

10: decimal[edit]

A majority of traditional number systems are decimal. This dates back at least to the ancient Egyptians, who used a wholly decimal system. Anthropologists hypothesize this may be due to humans having five digits per hand, ten in total.^[17]^[20] There are many regional variations including:

Western system: based on thousands, with variants (see English numerals)
Indian system: crore, lakh (see Indian numbering system. Indian numerals)
East Asian system: based on ten-thousands (see below)

12: duodecimal[edit]

Duodecimal systems are based on 12.

These include:

Chepang language of Nepal,
Mahl language of Minicoy Island in India
Nigerian Middle Belt areas such as Janji, Kahugu and the Nimbia dialect of Gwandara.
Melanesia^{[citation needed]}
reconstructed proto-Benue–Congo

Duodecimal numeric systems have some practical advantages over decimal. It is much easier to divide the base digit twelve (which is a highly composite number) by many important divisors in market and trade settings, such as the numbers 2, 3, 4 and 6.

Because of several measurements based on twelve,^[21] many Western languages have words for base-twelve units such as dozen, gross and great gross, which allow for rudimentary duodecimal nomenclature, such as «two gross six dozen» for 360. Ancient Romans used a decimal system for integers, but switched to duodecimal for fractions, and correspondingly Latin developed a rich vocabulary for duodecimal-based fractions (see Roman numerals). A notable fictional duodecimal system was that of J. R. R. Tolkien’s Elvish languages, which used duodecimal as well as decimal.

16: hexadecimal[edit]

Hexadecimal systems are based on 16.

The traditional Chinese units of measurement were base-16. For example, one jīn (斤) in the old system equals sixteen taels. The suanpan (Chinese abacus) can be used to perform hexadecimal calculations such as additions and subtractions.^[22]

South Asian monetary systems were base-16. One rupee in Pakistan and India was divided into 16 annay. A single anna was subdivided into four paisa or twelve pies (thus there were 64 paise or 192 pies in a rupee). The anna was demonetised as a currency unit when India decimalised its currency in 1957, followed by Pakistan in 1961.

20: vigesimal[edit]

Vigesimal numbers use the number 20 as the base number for counting. Anthropologists are convinced the system originated from digit counting, as did bases five and ten, twenty being the number of human fingers and toes combined.^[17]^[23]
The system is in widespread use across the world. Some include the classical Mesoamerican cultures, still in use today in the modern indigenous languages of their descendants, namely the Nahuatl and Mayan languages (see Maya numerals). A modern national language which uses a full vigesimal system is Dzongkha in Bhutan.

Partial vigesimal systems are found in some European languages: Basque, Celtic languages, French (from Celtic), Danish, and Georgian. In these languages the systems are vigesimal up to 99, then decimal from 100 up. That is, 140 is ‘one hundred two score’, not *seven score, and there is no numeral for 400 (great score).

The term score originates from tally sticks, and is perhaps a remnant of Celtic vigesimal counting. It was widely used to learn the pre-decimal British currency in this idiom: «a dozen pence and a score of bob», referring to the 20 shillings in a pound. For Americans the term is most known from the opening of the Gettysburg Address: «Four score and seven years ago our fathers…».

24: quadrovigesimal[edit]

The Sko languages have a base-24 system with a sub-base of 6.

32: duotrigesimal[edit]

Ngiti has base 32.

60: sexagesimal[edit]

Ekari has a base-60 system. Sumeria had a base-60 system with a decimal sub-base (with alternating cycles of 10 and 6), which was the origin of the numbering of modern degrees, minutes, and seconds.

80: octogesimal[edit]

Supyire is said to have a base-80 system; it counts in twenties (with 5 and 10 as sub-bases) up to 80, then by eighties up to 400, and then by 400s (great scores).

799 [i.e. 400 + (4 x 80) + (3 x 20) + {10 + (5 + 4)}]’

Rules to Write Numbers from One to Fifty (1 to 50) Spelling

While writing the spelling of the digits from one to fifty (1 to 50), some rules have to be followed.

Rule 1: Grasping on place values: The positional value of the digits in a number can be expressed depending on where they are put. The first four place values depending on the position of the number 1 can be written as

1 – one’s place
10 – tens place
100 – hundreds
1000 – thousands place

Rule 2: The numbers from one to 20, 30…. 100 and 1000 can be referred to through the number names from one to fifty chart along with the spellings. For instance, the number name of 5 is five, the number name of 30 is thirty, and so on.

Rule 3: To write the number names of multiples of the number 100 and thousand, the number name of the digit in the 100’s place and the term “hundred” is written. For example, the number name of 400 is four hundred.

Rule 4: To author the number names of the rest of the other two or three-digit numbers, the expanded form is written. For the numbers (eleven – nineteen) as the final 2 digits, the ones and tens place is taken as one unit. The addends are spelt out and merged with their respective names. For instance, 54 = 50 + 4 and 54 in words is termed as fifty-four.

Strategy To Grasp Number Names Till 50

Number one to number ten number names: No trick as such exists. Memorise the numerals.

Number eleven to twenty number names: The numbers eleven and twelve are different cases. From the number thirteen onwards till nineteen a pattern exists that is the number + teen. Thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen and the number twenty is varied.

Number twenty one to thirty number names: A pattern exists and it is written as twenty + one, twenty + two, twenty + three…… thirty is different.

Number thirty-one to forty number names: thirty + one, thirty + two…… forty is different.

Number forty-one to fifty number names: forty + one, forty + two…… fifty is different.

Importance of Names of Numbers

The names of the numbers are essential for each student to know. These are basic maths that will help students to spell the numbers correctly. Also, when they attend the classes and their teachers spell such numbers, then they can easily write them.

Numbers play a key role in Mathematics. All the mathematical or arithmetical operations are based on these numbers, not only in primary classes but in higher-level courses too.

Solved Problems on Number Name 1 to 50

Problem 1:

Solve and put down the given expression in words. 320 + 97 – (120 + 260)

Answer:

Now, we have to simplify the expression: 320 + 97 – (120 + 260)

First, simplify the expression inside the bracket

320 + 97 – (120 + 260) = 320 + 97 – 380

320 + 97 – (120 + 260) = 37 = Thirty-seven.

Hence, the simplified expression of 320 + 97 – (120 + 260) is 37.

Thus, the number 37 in words is thirty-seven.

Problem 2:

Find the answer of (one hundred and twenty-one) – (seventy-eight).

Answer:

In the form of numbers, one hundred and twenty-one is expressed as 121, and seventy-eight is expressed as 78.

The given problem is (one hundred and twenty-one) – (seventy-eight).

= (121 – 78)

= 43

On utilising the number name chart from 1 to 50, 43 can be expressed as follows.

43 = 40 + 3 = Forty + Three = Forty Three

Practice Questions

A Sudoku puzzle is a grid of 81 numbers

A number is a concept from mathematics, used to count or measure. Depending on the field of mathematics, where numbers are used, there are different definitions:

People use symbols to represent numbers; they call them numerals. Common places where numerals are used are for labeling, as in telephone numbers, for ordering, as in serial numbers, or to put a unique identifier, as in an ISBN, a unique number that can identify a book.
Cardinal numbers are used to measure how many items are in a set. For example, {A,B,C} has size «3».
Ordinal numbers are used to specify a certain element in a set or sequence (first, second, third).

Numbers are also used for other things like counting. Numbers are used when things are measured. Numbers are used to study how the world works. Mathematics is a way to use numbers to learn about the world and make things. The study of the rules of the natural world is called science. The work that uses numbers to make things is called engineering.

Numbering methods[change | change source]

Numbers for people[change | change source]

There are different ways of giving symbols to numbers. These methods are called number systems. The most common number system that people use is the base ten number system. The base ten number system is also called the decimal number system. The base ten number system is common because people have ten fingers and ten toes. There are 10 different symbols {0, 1, 2, 3, 4, 5, 6, 7, 8, and 9} used in the base ten number system. These ten symbols are called digits.^[1]

A symbol for a number is made up of these ten digits. The position of the digits shows how big the number is. For example, the number 23 in the decimal number system really means (2 times 10) plus 3. Similarly, 101 means 1 times a hundred (=100) plus 0 times 10 (=0) plus 1 times 1 (=1).

Numbers for machines[change | change source]

Another number system is more common for machines. The machine number system is called the binary number system. The binary number system is also called the base two number system. There are two different symbols (0 and 1) used in the base two number system. These two symbols are called bits.^[2]

A symbol for a binary number is made up of these two bit symbols. The position of the bit symbols shows how big the number is. For example, the number 10 in the binary number system really means 1 times 2 plus 0, and 101 means 1 times four (=4) plus 0 times two (=0) plus 1 times 1 (=1). The binary number 10 is the same as the decimal number 2. The binary number 101 is the same as the decimal number 5.

Names of numbers[change | change source]

English has special names for some of the numbers in the decimal number system that are «powers of ten». All of these power of ten numbers in the decimal number system use just the symbol «1» and the symbol «0». For example, ten tens is the same as ten times ten, or one hundred. In symbols, this is «10 × 10 = 100». Also, ten hundreds is the same as ten times one hundred, or one thousand. In symbols, this is «10 × 100 = 10 × 10 × 10 = 1000». Some other powers of ten also have special names:

1 – one
10 – ten
100 – one hundred
1,000 – one thousand
1,000,000 – one million

When dealing with larger numbers than this, there are two different ways of naming the numbers in English. Under the «long scale», a new name is given every time the number is a million times larger than the last named number. It is also called the «British Standard». This scale used to be common in Britain, but is not often used in English-speaking countries today. It is still used in some other European nations.

Another scale is the «short scale», under which a new name is given every time a number is a thousand times larger than the last named number. This scale is a lot more common in most English-speaking nations today.

1,000,000,000 – one billion (short scale), one milliard (long scale)
1,000,000,000,000 – one trillion (short scale), one billion (long scale)
1,000,000,000,000,000 – one quadrillion (short scale), one billiard (long scale)

Types of numbers[change | change source]

Natural numbers[change | change source]

Natural numbers are the numbers which we normally use for counting: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. Some people say that 0 is a natural number, too. The set of all natural numbers is written as .^[3]

Another name for these numbers is positive numbers. These numbers are sometimes written as +1 to show that they are different from the negative numbers. But not all positive numbers are natural (for example, ${displaystyle {tfrac {1}{2}}}$ is positive, but not natural).

If 0 is called a natural number, then the natural numbers are the same as the whole numbers. If 0 is not called a natural number, then the natural numbers are the same as the counting numbers. So if the words «natural numbers» are not used, then there will be less confusion about whether zero is included or not. But unfortunately, some say that zero is not a whole number, while others say that whole numbers can be negative. «Positive integers» and «non-negative integers» are another way to include zero or exclude zero, but only if people know those words.

Negative numbers[change | change source]

Negative numbers are numbers less than zero.

One way to think of negative numbers is to use a number line. We call one point on this line zero. Then we will label (write the name of) every position on the line by how far to the right of the zero point is. For example, the point one is one centimeter to the right, and the point two is two centimeters to the right.

However, the point one centimeter to the left of the zero point cannot be point one, since there is already a point called one. We therefore call this point minus one (−1, as it is one centimeter away but in the opposite direction).

A drawing of a number line is below.

All the normal operations of mathematics can be done with negative numbers:

Adding a negative number to another is the same as taking away the positive number with the same numerals. For example, 5 + (−3) is the same as 5 − 3, and equals 2.
Taking away a negative number from another is the same as adding the positive number with the same numerals. For example, 5 − (−3) is the same as 5 + 3, and equals 8.
Multiplying two negative numbers together produces a positive number. For example, −5 times −3 is 15.
Multiplying a negative number by a positive number, or multiply a positive number by a negative number, produces a negative result. For example, 5 times −3 is −15.

Since finding the square root of a negative number is impossible for real numbers (as negative times negative equals positive for real numbers), the square root of -1 is given a special name: i. This is also called the imaginary unit.^[3]

Integers[change | change source]

Integers are all the natural numbers, all their opposites, and the number zero.^[4] Decimal numbers and fractions are not integers.

Rational numbers[change | change source]

Rational numbers are numbers which can be written as fractions. This means that they can be written as a divided by b, where the numbers a and b are integers, and b is not zero.

Some rational numbers, such as 1/10, need a finite number of digits after the decimal point to write them in decimal form. The number one tenth is written in decimal form as 0.1. Numbers written with a finite decimal form are rational. Some rational numbers, such as 1/11, need an infinite number of digits after the decimal point to write them in decimal form. There is a repeating pattern to the digits following the decimal point. The number one eleventh is written in decimal form as 0.0909090909 … .

A percentage could be called a rational number, because a percentage like 7% can be written as the fraction 7/100. It can also be written as the decimal 0.07. Sometimes, a ratio is considered as a rational number.

Irrational numbers[change | change source]

Irrational numbers are numbers which cannot be written as a fraction, but do not have imaginary parts (explained later).

Irrational numbers often occur in geometry. For example, if we have a square which has sides of 1 meter, the distance between opposite corners is the square root of two, which equals 1.414213 … . This is an irrational number. Mathematicians have proved that the square root of every natural number is either an integer or an irrational number.

One well-known irrational number is pi. This is the circumference (distance around) of a circle divided by its diameter (distance across). This number is the same for every circle. The number pi is approximately 3.1415926535 … .

An irrational number cannot be fully written down in decimal form. It would have an infinite number of digits after the decimal point, and unlike 0.333333 …, these digits would not repeat forever.

Real numbers[change | change source]

Real numbers is a name for all the sets of numbers listed above:

The rational numbers, including integers
The irrational numbers

The real numbers form the real line. This is all the numbers that do not involve imaginary numbers.

Imaginary numbers[change | change source]

Imaginary numbers are formed by real numbers multiplied by the number i. This number is the square root of minus one (−1).

There is no number in the real numbers which when squared, makes the number −1. Therefore, mathematicians invented a number. They called this number i, or the imaginary unit.^[3]

Imaginary numbers operate under the same rules as real numbers:

The sum of two imaginary numbers is found by pulling out (factoring out) the i. For example, 2i + 3i = (2 + 3)i = 5i.
The difference of two imaginary numbers is found similarly. For example, 5i − 3i = (5 − 3)i = 2i.
When multiplying two imaginary numbers, remember that i × i (i²) is −1. For example, 5i × 3i = ( 5 × 3 ) × ( i × i ) = 15 × (−1) = −15.

Imaginary numbers were called imaginary because when they were first found, many mathematicians did not think they existed.^[5] The person who discovered imaginary numbers was Gerolamo Cardano in the 1500s. The first to use the words imaginary number was René Descartes. The first people to use these numbers were Leonard Euler and Carl Friedrich Gauss. Both lived in the 18th century.

Complex numbers[change | change source]

Complex numbers are numbers which have two parts; a real part and an imaginary part. Every type of number written above is also a complex number.

Complex numbers are a more general form of numbers. The complex numbers can be drawn on a number plane. This is composed of a real number line, and an imaginary number line.

           3i|_
             |
             |
           2i|_          . 2+2i
             |
             |
            i|_
             |
             |
 |_____|_____|_____|_____|_____|_____|_____|_____|

             |
           −i|_                .3−i
             |
             |
 .−2−2i   −2i|_
             |
             |
          −3i|_
             |

All of normal mathematics can be done with complex numbers:

To add two complex numbers, add the real and imaginary parts separately. For example, (2 + 3i) + (3 + 2i) = (2 + 3) + (3 + 2)i= 5 + 5i.
To subtract one complex number from another, subtract the real and imaginary parts separately. For example, (7 + 5i) − (3 + 3i) = (7 − 3) + (5 − 3)i = 4 + 2i.

To multiply two complex numbers is more complicated. It is easiest to describe in general terms, with two complex numbers a + bi and c + di.

For example, (4 + 5i) × (3 + 2i) = (4 × 3 − 5 × 2) + (4 × 2 + 5 × 3)i = (12 − 10) + (8 + 15)i = 2 + 23i.

Transcendental numbers[change | change source]

A real or complex number is called a transcendental number if it can not be obtained as a result of an algebraic equation with integer coefficients.

${displaystyle a_{n}x^{n}+dots +a_{2}x^{2}+a_{1}x+a_{0}=0}$

Proving that a certain number is transcendental can be extremely difficult. Each transcendental number is also an irrational number. The first people to see that there were transcendental numbers were Gottfried Wilhelm Leibniz and Leonhard Euler. The first to actually prove there were transcendental numbers was Joseph Liouville. He did this in 1844.

Some well-known transcendental numbers include:

e
π
e^a for algebraic a ≠ 0
${displaystyle 2^{sqrt {2}}}$

What is Number in Words?

Alphabetical form of numbers is called writing numbers in words. These are numbers written in words as the name implies. In the English language, the number 100, for example, is written as one hundred. All natural numbers, such as ones, tens, hundreds, thousands, and so on, can be represented in words based on the place value of their digits.

What is a Number Name?

Number name is the method of representing numbers in words. The alphabetical form of numbers is called number words. These are numbers written in words as the name implies. In language, the number 100, for example, is written as one hundred. All natural numbers, such as ones, tens, hundreds, thousands, and so on, can be represented as number names based on the place value of their digits.

Examples: 128 = 100 + 20 + 8. One hundred and twenty-eight is the number name of 128.

412 = 400 + 10 + 2 = 400 + 10 + 2 = 400 + 10 + 2 = 400 + 10 + 2 = 400 + 10 + 2 = 400 + 10 + 2 = 400 + 12. As a result, the number 412’s name is Four Hundred and Twelve.

685 = 600 + 80 + 5. = 685 = 600 + 80 + 5. Six hundred eighty-five is the number name for 685.

How to write a Number in Words using International System?
