# Solution Review : Check Parity of a Number

This lesson gives a detailed review of how to check the parity of a number.

## We'll cover the following

## Solution: Use Modulus`(%)`

Operator

The solution isn’t complicated. You simply check the **remainders** when even and odd numbers are divided by 2; all **even** numbers result in a **remainder of 0** and all **odd** numbers produce a **remainder of 1**. This is convenient because the problem requires us to return a 0 if a number is even, and a 1 if it is odd.
Therefore, you will just use the `%`

operator to obtain the remainder of n when divided by 2 and return the answer.
