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.
