Use tiles to find the sum or difference. 1.
6 + (-9) 2.
OK to draw out tiles….actually, quite smart thing to do.
+ + - -3 -6

2. DO NOT forget to “add the opposite!”3.
7 - 15 4.
OK to draw out tiles….too…
+ + + - -8

6 – (-13) 6.
-4 – (-10)
6 + 13
OK to draw out tiles….too… 19 6

4. Find the product. 7. 5(-10) 8. -7 · -6 - -50 42
Make sure to look at the signs FIRST! Do you need to add a neg sign to the answer FIRST? 7.

5. −3 2 − 5 2 (-3 · -3) - (5 · 5) 9 -25 Find the product. Show ALL work.
IMPORTANT….the exponent goes to the base and only the base……
and the base is the ONE ITEM in front of it! 9.

6. Find the product. Show ALL work.
Evaluate when x – 2, y = -3 and z = 4.
Rewrite the expression and use ( ) for variables…..then plug into the holes!!
