Natural numbers include the numbers: 1, 2, 3, 4,...

Their opposites include the numbers: -1, -2, -3, -4...

And with zero included, this set of numbers that consist of:

{...-4, -3, -2, -1, 0, 1, 2, 3, 4...} is called the set of **integers**.

The definition of natural numbers is whole numbers that are greater than zero (ex. 1, 2, 3, etc.). Fractions and negative numbers are not natural numbers, but are the opposite of natural numbers. These negative numbers can be called integers. Zero is considered an integer (it is not a fraction or irrational number).
