Adding Integers (2-2)

Adding Integers

Vocabulary:

Integers - The set of whole numbers and their opposites.
Absolute Value - The positive or negative integers distance from zero on the number line.
                             (Think spaces from 0). The absolute value is always positive or zero.

Positive + Positive = Positive

5 + 4 = 9

Negative + Negative = Negative

(- 7) + (- 2) = - 9

Sum of a negative and a positive number: Use the sign of the larger number and subtract

(- 7) + 4 = -3
6 + (-9) = - 3
(- 3) + 7 = 4
5 + ( -3) = 2
