## Counting Numbers

Counting numbers are the set of numbers that we use to learn how to count.

Example

1, 2, 3, 4, 5, and so on.

They are also called natural numbers, since they feel natural to us because they are naturally the first numbers to learn.

Sometimes they are also referred to as positive integers.
