There are many types of numbers used every day. Since this is not a math class, I’m only going to focus on three types of commonly used numbers — cardinal, ordinal, and nominal.
Cardinal numbers are used to count people and objects. For example: There are five stars.
Ordinal numbers are used to say the order or place of something or someone. For example: The fourth star is purple. Ordinal numbers are also used when saying or recording dates. For example: Today is March 3rd.
Nominal numbers are used to identify. For example: The red star is number one. Other examples of nominal numbers are cell phone numbers, zip codes, and house numbers.
