Name ________________________
1). (1 point each) Reduce your answers:
2). (1 point each) Use this number line to solve these problems:
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
-7 -6 -5 -4 -3 -2 -1 0 +1 +2 +3 +4 +5 +6 +7 +8 +9
a). 6 - 8 = |
b). - 4 - 2 = |
c). - 6 + 10 = |
3). (1 point each) Draw a circle around the double signs, replace them
with a single sign, then solve: (I'll do the first one for you!)
a). |
b). 4 + +4 = 4 4 =
|
c). 6 - - 2 = 6 2 =
|
d). 3 - + 4 = 3 4 =
|
The next problems have parentheses, but you do them the same way:
e).
|
f). 6 + (- 2) = 6 2 =
|
g). 12 - (- 8) = 12 8 =
|
h). 7 + (+ 4) = 7 4 =
|
i). - 4 - (- 5) = -4 5 =
|
j). 1 - (+ 8) = 1 8 =
|
k). 5 + (- 5) = 5 5 =
|
l). 4 - (- 4) = 4 4 = |
