Addition and Subtraction of Integers (Rules and Examples)

When the numbers have the same sign, always add and keep these in mind:

Positive + Positive = PositiveNegative + Negative = Negative

The sign for Positive + Negative or Negative + Positive depends on which number has the bigger absolute value.

Rule

Always subtract the absolute values and keep the sign of the number with the higher absolute value!

For example, −8 + 5 = −3 but −5 + 8 = 3.

Common mistake

Keeping the sign of the bigger number. In −8 + 5, 5 is bigger than −8, but −8 has the bigger absolute value (8 is more than 5), so the answer is negative: −8 + 5 = −3.

Rule

To subtract an integer, add its opposite. For example, 7 − (−3) = 7 + 3 = 10 and 4 − 9 = 4 + (−9) = −5.
