Add the two numbers and use the same sign.
Different Signs:
Subtract the two numbers, use the sign of the number with the larger absolute value.
Rule:
To subtract an integer, add its opposite.
(Make two marks.)
Subtracting Integers
Rules for Multiplying IntegersRules:
Positive x Positive = Positive
Positive x Negative = Negative
Negative x Positive = Negative
Negative x Negative = Positive
+ • + = ++ • - = -- • + = -- • - = +
Rules for Dividing IntegersRules: Same as Multiplying
Positive ÷ Positive = Positive
Positive ÷ Negative = Negative
Negative ÷ Positive = Negative
Negative ÷ Negative = Positive
+ ÷ + = ++ ÷ - = -- ÷ + = -- ÷ - = +
