# Cardinal Numbers? Definition and Examples Cardinal numbers are one of the fundamental concepts in mathematics. These numbers represent the quantity or size of a set, and they are used to count and measure things.

## What is a Cardinal Number?

A cardinal number is a number that represents a quantity or size of a set. These numbers are used to count or measure things and are typically represented using numerals. For example, the number “3” is a cardinal number that represents a set of three objects or elements.

## Types of Cardinal Numbers

There are two types of cardinal numbers: finite and infinite. Finite cardinal numbers are used to represent a finite set of objects or elements. Examples of finite cardinal numbers include 0, 1, 2, 3, 4, and so on. Infinite cardinal numbers are used to represent an infinite set of objects or elements. The most commonly known infinite cardinal number is “infinity,” which represents an unbounded quantity.
