Sign Rules for Multiplication and Division of integers:
Sign rules for Addition and Subtraction of integers:
Same signs add and different signs subtract.
If the numbers have the same sign keep the sign. (Ex.) -3 + (-7) = -10 ==> - 3 - 7 = -10
If the numbers have different signs keep the sign of the larger. (Ex.) 4 + (-2) = 2 ==> 4 - 2 = 2
When subtracting integers keep the first number, change the operation into addition and then change the second number to its opposite. (Ex.) -3 - (-7) ==> -3 + 7 = 4 (Ex.) -4 - 2 ==> -4 + (-2) use the 1st rule for addition.
