# Even and Odd Numbers

Table of Contents

## Even Numbers

Any integer that can be divided exactly by 2 is an even number.

The last digit is 0, 2, 4, 6 or 8

Example: −10, -4, 0, 8, and 32 are all even numbers

## Odd Numbers

Any integer that cannot be divided exactly by 2 is an odd number.

The last digit is 1, 3, 5, 7 or 9

Example: -13, −9, 1, 5, and 27 are all odd numbers

Odd numbers are in between the even numbers.

## Adding and Subtracting

When we add (or subtract) odd or even numbers the results are always:

 Operation Result Example Even + Even Even 4 + 6 = 10 Even + Odd Odd 6 + 1 = 7 Odd + Even Odd 7 + 6 = 13 Odd + Odd Even 1 + 5 = 6

The same thing happens when we subtract instead of adding.

## Multiplying

When we multiply odd or even numbers the results are always:

 Operation Result Example Even × Even Even 4 × 6 = 24 Even × Odd Even 2 × 7 = 14 Odd × Even Even 5 × 4 = 20 Odd × Odd Odd 7 × 5 = 35
