1. Multiplying and Dividing Integers
A REVIEW OF THE RULES

2. Rules When multiplying and dividing integers there are two rules:
When multiplying or dividing integers that have the SAME sign, the answer is POSITIVE.
Positive x positive = positive
Negative x negative = positive
+7 x +12 = +84
-6 x –5 = +30

3. Rules continued… Rule 2:
When multiplying or dividing integers whose signs are DIFFERENT, the answer will always be NEGATIVE.
Positive x negative = negative
Negative x positive = negative
+8 x –4 = -32
-5 x +7 = -35

4. Let’s Practice!
What sign would the answer have in front of the integer???
-5 x -6 = ???

5. POSITIVE!

6. What sign will be in front of the answer??
How about…
-6 x 8 = ???
What sign will be in front of the answer??

7. NEGATIVE!

8. Try this one!
What sign will be in front of the answer???
-72÷ +9 = ???

9. NEGATIVE!

10. Let’s TRY SOLVING some problems:
-6 x –4 =

11. 24

12. 4 x 11 =

13. 44

14. 45 ÷ -5 =

15. -9

16. -70 ÷ 7 =

17. -10

18. 8 x –11 =

19. -88

20. Different signs = a negative
So Remember…
When multiplying and dividing integers:
Same signs = a positive
Different signs = a negative
