c) -9 - (- 7) = d) + 3 - (+9) =
e) -9 - (-5) = f) -16+ (+5) =
g) +2 - (+2) = h) -8 – (+4) =
i) +9 - (+2) = j) -4 - (-11) =

Answer 1

a) + 8 - ( + 8) = 8 - 8 = 0

b) - 7 - ( - 2) = - 7 + 2 = - 5

c) - 9 - ( - 7) = - 9 + 7 = - 3

d) + 3 - ( + 9) = 3 - 9 = - 6

e) - 9 - ( - 5) = - 9 + 5 = - 4

f) - 16 + ( + 5) = - 16 + 5 = - 11

g) + 2 - ( + 2) = 2 - 2 = 0

h) - 8 - ( + 4) = - 8 - 4 = - 12

i) + 9 - ( + 2) = 9 - 2 = 7

j) - 4 - ( - 11) = - 4 + 11 = 7
