Ordinal Numbers vs. Cardinal Numbers

The main difference between the ordinal numbers and cardinal numbers is the use. A cardinal number is a number that how many of something there and the ordinal number is a number that tells the position of something in a list.

Therefore, ordinal numbers do not quantify the noun, like the cardinals, but rather identify and individualize it within an ordered set of elements of the same class.

Some examples of the use of cardinal numbers in English:

Dates

  • Ex: She was born in 1998.

Count

  • Ex: I have three brothers.

To say your age

  • Ex: I am twenty years old.

A phone number

  • Ex: My phone number is 202-555-0130

In the case of ordinary numbers, they are used for dates, orders, names of kings and queens, anniversaries, and floors.

In short, cardinal numbers signify quantity whereas ordinal numbers signify order and position.
