Cardinal Numbers - Meaning, Examples, Sets
Cardinal numbers are numbers that are used for counting. They are also known as natural numbers or cardinals. A set of cardinal numbers starts from 1 and it goes on up to infinity. We use cardinal numbers to answer the question "how many?". For example, how many students are going to the school picnic? The answer could be any number like 20, 23, 30, etc. So, all these numbers come in the category of cardinal numbers. In this article, we will explore the world of cardinal numbers and understand the difference between cardinal and ordinal numbers.

What are Cardinal Numbers?
A cardinal number describes or represents how many of something are present. Example 2 apples, 5 flowers, etc. It quantifies an object. It does not have values as fractions or decimals. Cardinal numbers are counting numbers, they help to count the number of items. Let's have a look at cardinal numbers examples. Ana wants to count the number of people standing in a queue at a billing counter. Can you help her? Ana started to count using Natural numbers.
Ana counted 1, 2, 3, 4, and 5. There are 5 people standing in a queue at the billing counter. Counting numbers are cardinal numbers! Now, Let's consider another example, Noah kept eight apples in a basket. The number eight denotes how many apples are there in the basket, irrespective of their order.
Examples of cardinal numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, and so on. The smallest cardinal number is 1 as 0 is not used for counting, so it is not a cardinal number.
Difference Between Cardinal and Ordinal Numbers
All the natural numbers are also referred to as cardinal numbers. Cardinal numbers are used for counting. While an ordinal number is a number that denotes the position or place of an object. Example: 1st, 2nd, 3rd, 4th, 5th, etc. Ordinal numbers are used for ranking. Here is an example that explains cardinal and ordinal numbers:
In the above image, we can see a team of 4 workers on the construction site. This is an example of cardinal numbers.
In the above image, we can see the position of the runners in the running event. First, second, third, and so on. This is an example of ordinal numbers. Let's discuss ordinal and cardinal number differences in the table below:
Cardinal Numbers | Ordinal Numbers |
---|---|
They are counting numbers that represent quantity. | They are based on the rank or position of an object in a given list or order. |
Cardinal numbers give us the answer of 'how many?'. | Ordinal numbers give us the answer of 'where'. For instance, where does the object lies in the list? |
Examples are 1, 2, 3, 4, 5, 10, etc. | Examples are 1st, 2nd, 3rd, 4th, 5th, 10th, etc. |
List of Cardinal Numbers from 1 to 100
Given below are the basic and most important cardinal numbers, which form the base for other counting numbers.
1 - One | 6 - Six |
2 - Two | 7 - Seven |
3 - Three | 8 - Eight |
4 - Four | 9 - Nine |
5 - Five | 10 - Ten |
10 - Ten | 60 - Sixty |
20 - Twenty | 70 - Seventy |
30 - Thirty | 80 - Eighty |
40 - Forty | 90 - Ninety |
50 - Fifty | 100 - Hundred |
Given below is the list of all cardinal numbers from 1 to 100. It will also help you to see how we write cardinal numbers in words like 21- twenty-one.
Cardinal Numbers of a Set
In the case of a set, the cardinal number is the total number of elements present in it. In other words, the number of distinct elements present in a set is the cardinal number of the set. The cardinal number of a set A is represented as n(A). For example, the cardinal number of set W = {1, 3, 5, 7, 9} is n(W)=5, as there are 5 elements in it.
Think Tank:
- Maria wrote January 1, 2020, as today’s date in her notebook. Does the number 1 in the date, represent a cardinal number?
- There are _______ people in the line ahead of me. I am the 7th person in the line.
Important Notes:
- Cardinal numbers help us to count the number of things or people in or around a place or a group.
- The collection of all the ordinal numbers can be denoted by the cardinal.
- Cardinal numbers can be written as words such as one, two, three, etc.
- Cardinal numbers tell how many items, whereas ordinal numbers show position or ranking.

Cardinal Numbers Examples
-
Example 1: Kate has a list of numbers as shown - 7, 8th, 10, Two, Fourth, 2nd. Identify the cardinal numbers.
Solution:
7, 10 and two help us in counting, whereas 8th, fourth and 2nd helps us in identifying the position. Thus, 7, 10, and two are cardinal numbers.
-
Example 2: Help Ryan, to calculate the number of vowels in "NUMBERS". Also, identify the number of alphabets used to form this word.
Solution:
(i) We know that a, e, i, o, and u are the vowels and in the given word u and e are used. Therefore, 2 vowels are used to form this number (2 is the required cardinal number).
(ii) We start counting from N to S, we see that "Numbers" has 7 alphabets in all. Therefore, a total of 7 alphabets are required to form the given word and here 7 is a cardinal number.

thousand - thousand,
million - millions,

The numeral one is consistent with nouns in all cases:one friend, one friend, one friend, one friend, about one friend .
- After the numerals two, three, four nouns are in the genitive singular :
two friends , three bananas , four birches .
After all other numerals, nouns stand in the genitive plural :seven friends , forty bananas , one hundred birches .
In all cases, except for the nominative, the numerals will agree with the nouns:no two friends, approached two friends, proud of two friends, talked about two friends .
Digits
Cardinal numbers are divided into digits:
- Integers (denoting an integer):
one, twenty-five, one hundred .
- Fractional (denoting a fractional number):
three fifths, one eighth .
Fractional numbers consist of two parts: the first part is the numerator of the fraction is a cardinal number in the nominative case, the second part is the denominator of is the ordinal number in the genitive plural:one tenth, two sevenths .
Fractional numbers are written separately.
In colloquial speech, some fractional numbers have specific names:
one second - half , one third - third , one fourth - quarter .
Nouns after fractional numbers are always put in the genitive singular:half an apple, three fourths of the area, a quarter of a kilogram .
The word and a half also belongs to fractional numbers, which has only two forms:M. and Wed. genus J. Rod I., V. One and a half FILE R., D., T., P. 9011 9019 - Collective (total 11 pieces):
two, three, four, five, six, seven, eight, nine, ten ;
both (both, both), both (both).
Collective numerals denote the number of persons or objects as a single group, something united and inseparable:two sisters, four friends .
Collective numbers combined:
- With nouns that are used only in the plural:
two points, three sleds .
- With masculine nouns denoting people and baby animals:
three friends, five kittens .
Regular quantitative nouns can also be combined with these nouns:three friends - three friends, five kittens - five kittens .

Cardinal numbers from 1 to 100
As in Russian, there are numbers in English, with the help of which we count something. They are called "quantitative" ( cardinal numbers ), answer the question "how much?": one - one, two - two. And also there are numerals that are responsible for the order of something when counting. These numbers are called “ordinal” ( ordinal numbers ) and answer the question “what is the number?”: first is the first, second is the second.
- We advise you to study the article on ordinal numbers in our blog separately.
These are the numbers you can see in English.

Look like a native speaker Ronnie says these numbers in English. Try to repeat after her to get used to the correct pronunciation and stress in these words.
Cardinal numbers in English are:
- Simple: one (1), three (3), hundred (100), thousand (1000).
- Derivatives, that is, those that have the suffixes - teen and - ty : seventeen (17), fifty (50).
- Compounds that include two or more words: eight hundred (800), five hundred and forty-three (543), six thousand, three hundred and ninety-nine (6399).
Cardinal numbers from 100 to ...
And this is how cardinal numbers over a hundred are formed.
101 – one hundred and one |
102 - one hundred and two |
200 – two hundred |
300 – three hundred |
1000 – one thousand |
1001 – one thousand and one |
1346 - one thousand, three hundred and forty-six |
3000 – three thousand |
10 000 – ten thousand |
100 000 - one hundred thousand |
1,000,000 – one million |
1,000,000,000 – one milliard (more common in England) and one billion (more common in USA) |
Let's try to do the impossible and write down in words such a number 1 623 457?
1,623,457 = One million , six hundred and twenty-three thousand
According to the classical rules of English, when we write numbers in words, then after each “three” of digits we must put a comma (1. 346 - one thousand, three hundred and forty-six ), but in modern English they may not be separated in writing comma every thousandth place. When we write compound quantitative numbers in digits, we separate every three digits with a comma: 6 , 485 or 15 , 394. But in decimal fractions we use a point - 2.5 or 4.46. And in Russian, everything is completely opposite: we use a comma with fractions, and a dot with digits.
Features of the use of cardinal numbers in English
Let's talk about some features of the use of cardinal numbers.
- Look at the numbers from 13 to 19. Did you see a pattern? Yes, these numerals are formed with the help of the suffix - teen from the numerals of the first ten. Watch out for minor spelling changes in 13 ( thirteen ) and 15 ( fifteen ). Pronounce such numbers correctly: the stress will be on this suffix - teen .
- Numerals expressing tens are also formed. We work with the numbers of the first ten and the suffix - ty . And notice that there is a hyphen between the tens and subsequent ones ( fifty-five , sixty-three , ninety-one ).
- If you were attentive, you must have noticed that the numbers hundred , thousand and million do not have a plural when they are preceded by another number: seven hundred , five thousand , nine million . However, if we are talking about some indefinite amount and a noun follows after the numeral, then the ending - s is possible.
Millions of people voted in this election. Millions of people voted in this election.
Three hundred people voted for him. Three hundred people voted for him.
- If you come across the phrases "five hundred workers" or "four thousand students", you will certainly want to translate them using the preposition of , but this is not necessary. It is correct to say five hundred workers and four thousand students . When we say “four of my sisters” and mean “four of all my sisters”, “ten of your articles” (ten of all your articles), “three of his colleagues” (three of all his colleagues), we use the preposition of when translating: four of my sisters , ten of your articles , three of his collegues .
- In the phrases “thirty-one novels” or “sixty-one weeks”, students think that when translating into English, the words “romance” and “week” should be in the singular. And here it is not. They are translated by plural nouns: thirty-one novels and sixty-one weeks .
As you can see, nothing complicated. This topic is closely related to other numbers that you need to pay attention to:

- "Ordinal numbers in English"
- "Dates and Ordinal Numbers in English"
- Fractional Numbers in English
