1). 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). +8 - 10 = |
b). - 3 - 4 = |
c). - 7 + 15 = |
2). Multiply these numbers:
a). +5 x - 2 =
|
b). +3 x - 4 =
|
c). - 8 x - 8 =
|
d). - 6 x +4 =
|
e). +6 x (- 3) =
|
f). - 9 x (- 8) =
|
g). - 7 x (+3) =
|
h). (- 5) x (- 4) =
|
3). Draw a circle around the double signs, replace them with a single
sign, then evaluate:
a).
|
b). +9 - -2 = +9  2 =
|
c). - 5 + -2 = - 5 2 =
|
d). +8 - (- 4) = +8 4 =
|
e). - 2 - (- 2) = - 2 2 =
|
f). +7 - (+4) = +7 4 =
|
| g). +11 + (-8) = +11 8 = |
