A positive number, also known as a positive integer, is a number that is bigger than zero. The set of all positive integers is written as [math]{Z}_+[/math].[1]

A positive number can be written with a "+" symbol in front of it, or just as a number.[2] For example, the numbers "+3" and "3" stand for the same numbers.

Positive numbers are written to the right of zero on a number line:
