2. Multiplication and Division of Integers

3. Multiplying! / Steps: / Ignore signs and multiply / Determine the sign / Positive times a Positive = Positive / Positive times a Negative = Negative / Negative times a Positive = Negative / Negative times a Negative = Positive / Steps: / Ignore signs and multiply / Determine the sign / Positive times a Positive = Positive / Positive times a Negative = Negative / Negative times a Positive = Negative / Negative times a Negative = Positive

4. Here’s a way I can Remember! / To remember whether your answer will be positive or negative when MULTIPLYING or DIVIDING, we’ll use:

5. Another way to Remember! / Same signs are always positive / Opposite signs are always negative / Same signs are always positive / Opposite signs are always negative

6. When multiplying Integers, cover the Two signs you are using Ex.: 5 (-3) What sign is left uncovered? Negative, - That is the sign of The answer = -15

7. Examples (-10)(3) = 21  -5 = -13  -6 =
