Multiplying Integers - Rules

Positive x Positive = PositivePositive x Negative = NegativeNegative x Positive = NegativeNegative x Negative = Positive

Skip A & B

Divide the absolute values of the two numbers (ignore the signs), then decide which sign to use.If the signs are the same, the quotient will be positive. If the signs are different the quotient will be negative.

Positive ÷ Positive = PositivePositive ÷ Negative = NegativeNegative ÷ Positive = NegativeNegative ÷ Negative = Positive

Dividing Integers - Rules

No! Division in NOT commutative. When you change the order, you get quotients that are multiplicative inverses of one another!

Adding zero to ANY rational number does NOT change the value of the number.

Yes! The multiplicative identity is 1.

The sum of a number and its opposite (additive inverse) is always zero!

Each nonzero rational number has a multiplicative inverse. It is the reciprocal of the number. A number times its multiplicative inverse is equal to one!

Zero is its own additive inverse.
