h) −(−3 − 1) − (−6 + 4 − 1) − 6 − (−3 + 2) =

Answer 1

Resposta:

a) a) (+3) + (– 2) = 1

b) (– 2) – (+1) = -3

c) (+4) + (– 2) – (+3) = -1

e) (+4) + (– 6) – (+7) – (– 6) + (+7) = -3

f) (– 3) – (– 5) + (– 6) + (+8) – (– 4) = 8

g) + (– 3 + 8) – (– 3 + 8) + (5– 6) = -1

h) −(−3 − 1) − (−6 + 4 − 1) − 6 − (−3 + 2) = 2
