Math Exam Review

Integers

Negative numbers represent 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 subtration statement

Opposite integers have the same numeral but different sign eg. 3 and (-3)

Know wat a (+)+(+)= (+)-(+)=
(-)+(-)= (-)-(-)=
(+)+(-)= (+)-(-)=
(-)+(+)= (-)-(+)=

practice with different numerals in each situation
