## What are the even numbers?

Even numbers are those that can be divided by 2 and result in an exact number, therefore, an even number cannot have decimals.

Another alternative to check if a number is even is when the last digit or digit is 0, 2, 4, 6 or 8.

Note: The number 0 is considered as an even number.

In mathematical form there are 2n, where n is an integer, for example: Check if 32 is an even number:

2n = 32
n = 32/2 = 6

Therefore, 32 is an even number.

Note: Negative numbers can also be even.

## Operations with even numbers

### Add and Subtract to get an even number

When adding or subtracting an even number with another even number the result is an even number.

even number + even number = even number

When adding or subtracting an odd number with an odd number, the result is an even number.

odd number + odd number = even number

### Multiplication to obtain an even number

When multiplying an even number by another even number the result is an even number

even number x even number = even number

When multiplying an even number by an odd number the result is an even number.

even number x odd number = even number
odd number x even number = even number

## Even numbers from 1 to 100

The table shows even numbers with blue background.

 2 4 6 8 10 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 61 63 65 67 69 71 73 75 77 79 81 83 85 87 89 91 93 95 97 99

The even numbers from 1 to 100 are: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98 and 100.

It is possible to observe from the table that every even number has the last number the number 2, 4, 6, 8 or 0 and every number with a white background color corresponds to the odd numbers.
