1. Multiplying and Dividing Integers
Objective: SWBAT multiply or divide two integers and give the answer the correct sign.

2. Vocabulary
Integer are whole numbers and their opposites
Sign a number that is either positive or negative
Positive -- +
Negative -- -
Product means to multiply
Quotient means to divide

3. 9 Rules for Multiplying and Dividing Integers:
Multiply and/or Divide the integers without regards to the sign, then give your answer a sign using these rules.
Same Signs – Multiply or Divide, then make your answer positive.
Pos. ∙ Pos. = Pos.
5 ∙ 4 = 20
2 ∙ 3 = 6
Pos. ÷ Pos. = Pos.
10 ÷ 5 = 2
36 ÷ 4 = 9
Neg. ∙ Neg. = Pos.
-6 ∙ -2 = 12
-3 ∙ -8 = 24
Neg. ÷ Neg. = Pos.
-12 ÷ -4 = 3
-5 ÷ -1 = 5

4. Different Signs – Multiply or Divide, then make your sign negative.
Pos. ∙ Neg. = Neg.
2 ∙ -4 = -8
8 ∙ -2 =
-16
Pos. ÷ Neg. = Neg.
15 ÷ -3 = -5
9 ÷ -3 = -3
Neg. ∙ Pos. = Neg.
-1 ∙ 4 = -4
-2 ∙ 9 =
-18
Neg. ÷ Pos. = Neg.
-14 ÷ 2 = -7
-24 ÷ 4 = -6

5. Mixed Practice
1. 8 ∙ -9 =
-72
÷ -4 = 5 = 3 -3
4. -5(-6) = 30
÷ -2 = -8
6. -4(2) =
7. (-4)2 =
-4 ∙ -4 = 16
8. (-3)3 =
-3 ∙ -3 ∙ -3 =
-27
