Cardinal numbers!!! Cardinal numbers are the numbers we count with and probably what you think of first when you hear the word “number.” For example, “one,” “two,” and “three” are all cardinal numbers.

## Cardinal Numbers

**Cardinal numbers** are used to count a set of objects and tell us about quantity. These are also said to be **cardinals**.

We use cardinal numbers to count (e.g., one, two, three). Typically, in formal writing, you will want to write out numbers up to ten as words and use numerals for larger values.

For numbers in the hundreds, the British usually say “and” but the Americans often do not say “and”.

- British English: 215 =
*two hundred***and**fifteen - American English: 215 =
*two hundred fifteen*
