Answer 1

A)  – 8 + 6 – 1 = -3

B) – 2 – 4 – 1 = -7

C) 12 – 7 + 3 = +8

D) 4 + 13 – 21 = - 4

E) (+8) – (+5) = +8 -5 = +3

F)  (– 8) + (– 5) = -8 -5 = -13

G)  (– 3) + (+ 9) = -3 +9 = +6

H)  (+ 2) + (– 7) = + 2 -7= -5

I)  – 13 + 7 – 2– 8 + 15 – 1 = -2

J)+ 22 – 3 – 14 – 5 + 24 + 12 = + 36

K) (– 2) – (– 3) + ( + 5) = -2 + 3 + 5 = +6

L)  ( + 6) + (– 7) – (– 2) =+ 6 - 7 +2 = +1
