**"how many."**Cardinal numbers are also known as "counting numbers," because they

**show quantity.**

**order of things in a set**—first, second, third, etc. Ordinal numbers do not show quantity. They only

**show**

**rank or position.**

**nominal number names something**—a telephone number, a player on a team. Nominal numbers do not show quantity or rank. They are used only to

**identify something.**
