Year 1 Homework #12

Name ________________________

1). (1 point each) Reduce your answers:
a).
b).
c).
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 = 44 =


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 =
