This tutorial will explain how to add integers (positive and negative numbers).

Integers are all whole numbers, including zero, and their opposites (negative numbers). On a horizontal number line all the numbers to the right of zero are positive and all the numbers to the left of the zero are negative. Integers do not include decimals or fractions.

When dealing with positive numbers, the farther away from zero the larger the value of the number.

When dealing with negative numbers, the closer to zero the larger value of the number.
