Cardinal Numbers

What is a Cardinal Number?

A cardinal number is a number that specifically signifies quantity. It represents "how many" of something there are, ranging from 0 (zero) to infinity. Cardinal numbers are used for counting and answering questions like 'How many apples are there?' These numbers, such as 1, 2, 3, 4, etc., contrast with ordinal numbers that denote position or order in a series like first, second, third, and so forth.

Cardinal Numbers From 1 to 20

Knowing the cardinal numbers from 1 to 20 provides you with the foundational language needed for basic counting in English. These are the building blocks, and understanding them is crucial. Here's a table to familiarize yourself with these terms:

Cardinal Numbers in Multiples of 10

After learning cardinal numbers 1-20, understanding numbers in English becomes much easier. From 30 onward, most numbers are simple combinations of tens and single units. Here are the cardinal numbers in multiples of 10:

NumberWord Equivalent
100One Hundred

By understanding these, you can form numbers such as '33' (thirty-three), '47' (forty-seven), and all the other numbers 1-100. These set the stage for combining numbers and are used frequently in daily conversation and writing. Being confident with these will enable you to comprehend and form any number between 20 and 100, and even beyond.


Hundreds of Cardinal Numbers 100 to 1000

Mastering hundreds of cardinal numbers from 100 to 1000 is a significant step in your English learning journey. 

NumberWord Equivalent
100One Hundred
200Two Hundred
300Three Hundred
400Four Hundred
500Five Hundred
600Six Hundred
700Seven Hundred
800Eight Hundred
900Nine Hundred
1000One Thousand

For numbers within these hundreds, you simply add the 'and' plus the rest of the number. For example, '375' would be 'three hundred and seventy-five'. This familiarity expands your ability to discuss quantities and prices, tell the time, talk about the weather (in terms of temperature), and more. Remember, for numbers between hundreds, just add 'and' plus the rest of the number. Keep practicing, and you will become comfortable with these numbers.

Larger Cardinal Numbers

Understanding larger cardinal numbers is essential for discussing quantities in the thousands and millions, such as populations, distances, or finances. These numbers follow the same pattern you've already learned, just on a larger scale. 

NumberWord Equivalent
1,000One Thousand
10,000Ten Thousand
100,000One Hundred Thousand
1,000,000One Million

Just remember, within these larger numbers, the pattern you've already learned repeats. For example, '1,234,567' would be 'one million, two hundred thirty-four thousand, five hundred and sixty-seven'.
