1. Multiplying integers 3(3) = 9 -3 2(3) = 6 -3 1(3) = 3 -3 0(3) = 0 -3
-1(3) = -3 -3
-2(3) = -6

2. Multiplying integers 3(4) = 12 -4 2(4) = 8 -4 1(4) = 4 -4 0(4) = 0 -4
-1(4) = -4 -4
-2(4) = -8

3. Multiplying integers + + + = + = + =

4. Multiplying integers -5(2) = -10 +5 -5(1) = -5 +5 -5(0) = 0 +5
-5(-1) = 5 +5
-5(-2) = 10

5. Multiplying integers + + + = + = + = + =

6. Multiplying integers Same signs = Positive Different signs = Negative

7. Multiplying integers
1(-2) = -2
-6(-3) = 18
On your own, try # 3, 4, 5

8. Let’s try the rules
-6 • 3 =
-18
-5 • -7 = 35
4 • -9 =
-36
3 • 7 = 21

9. -9 • -3 = 27
8 • -4 =
-32
-4 • 6=
-24
-5 • -3 = 15
-8 • 7 =
-56
9 • 7 = 63
3 • -4 =
-12
-18 • 10=
-180
2 • -8 =
-16
-25 • 6 =
-150

11. Worksheet A/B
#1-11 odd
