Exam Review

Integers
 Negative numbers represents values below zero and positive numbers represent values above zero.
eg: above and below ground or sea level
1+(-2)=(-1) is an addition statement
3-(-1)=4 is  a subtraction statement


Opposite integers have the same numeral but different sign.

(+) + (+) =
(-) - (-) =
(+) + (-) =
(-) + (+) =


(+) - (+) =
(-) - (-) =
(+) - (-) =
