Answer 1

Bom dia

a) -1 - 2 = -3 -3 = -6

b) -4 -5 = -9 -8 = -17 + 10 = -7

c) -7+ 20 = +13 - 15 = -2 + 20 = +18 - 1 = +17

d) +8 -10 = -2 - 7 = -9 + 13 = +4 - 14 = -10 + 5 = -5 - 6 = -11

e) -13 + 7 = -6 - 9 = -15 + 5 = -10 - 13 = -23

f) -20 + 10 = -10 - 10 = -20 + 20 = 0 + 14 = +14 - 13 = +1 - 1 = 0

g) -8 - 10 = -18 + 17 = -1 - 13 = -14 + 4 = -10 - 7 = -17 + 8 = -9 - 1 = -10

h) -6 -7 = -13 - 13 = -26 - 26 = -52 + 54 = +2 - 2 = 0
