cardinal number

A **cardinal number** is a number that expresses quantity or “how many” of something there are. Unlike ordinal numbers that indicate position or order (like first, second, third), cardinal numbers represent countable amounts, such as one, two, three, and so on. They are fundamental in mathematics and everyday counting, helping us quantify objects, people, or any countable items.
