Notice how positive and negatives are opposites going two different

directions

Integers

Subtracting IntegersAdding and subtracting integers is almost identical. We convert the subtraction symbol to addition and give the following number its opposite sign.

5 - 7Change – to + and opposite of 7 is -7

5 + -7

-2 - 3

= -2

-2 + -3

= -5Change – to + and opposite of 2 is -2 -2 – -8 -2 +

8= 6

Change – to + and opposite of -8 is 8
