Answer 1

Resposta:

Explicação passo-a-passo:

a) -4+9+6-4-3=  -11 + 9 = -2

b) (+8)-(+9)+(+4)-(-1)=  8 - 9 + 4 + 1 = 13 - 9 = 4

c) -(+5)+(-2)-(-4)+(+1)=  - 5 - 2 + 4 + 1 = -7 +5 = -2

d) +5-4+(-2)-(-1)=  5 - 4 - 2 + 1 = 6 - 6 = 0

e) (-3)-(-2)+(-4)-(+1)+(+6)=  -3 + 2 -4 - 1 + 6 = 8 - 8 = 0

f) -6-5-3-2+9-1= -17 + 9 = -8
