Integers Addition and Subtraction Review

1) 6 + 7 = 7 + 6

2) 9 – 3 = 3 – 9

3) |7| – |8| = |8| – |7|

4) (10 – 3) – 2 = 10 – (3 – 4)

5) (5 + 6) + 7 = 5 + (6 + 7)

Fill in the blanks.

6) 83 + 17 = 17 +

7) |46| – |50| =

8) 42 – 2 + (18 – 10) =

9) 18 – (3 – 1) =

10) 8 - 0 =

Answer 1

6.83+17=17+83
7.|46|-|50|=|50|-|46|
8.42-2+(18-10)=(18-10)+42-2
9.18-(3-1)=20
10.8-0=8

Answer 2

6) 83 + 17 = 17 + 83

7) |46| – |50| = |50| – |46|

8) 42 – 2 + (18 – 10) = 48

9) 18 – (3 – 1) = 16

10) 8 - 0 = -0+8
