Question

Column A Column B
1. (–22+17)+13 = –22+(17+13)
2. –(27+(–3)) = –27+3
3. 35+(–15+4) = (35+(–15))+4
4. –12+6 = 6+(–12)
a. commutative property
b. associative property
c. opposite of a sum property

Answer 1

1) (-22 + 17) + 13 = -22 + (17+13)
                - 5 + 13 = -22 + 30
                           8 = 8

2) -[27+(-3)] = -27+3
              -24 = -24

3) 35 + (-15+4) = [5+(-15)] + 4
         35 + (-11) = 20 + 4
                     24 = 24

4) -12 + 6 = 6 + (-12)
            - 6 = - 6

Answer: C
