Question

a) 20-{6-[-1+(3-6)-2]}=
b) -4-{-2+3+[-2-(6-9-3)]}=
c) [-19-(8-6+15)-3]-[15+(13-10+5)-2]=​

Answer 1

Resposta:

20-{6-[-1+(3-6)-2]}=8

-4-{-2+3+[-2-(6-9-3)]}= -9

[-19-(8-6+15)-3]-[15+(13-10+5)-2]=​ -60

Explicação passo a passo:

Answer 2

Resposta:

a) 20-{6-[-1+(3-6)-2]}

20 - (6 - (-1 - 3 - 2))

20 - (6 + 6) = 20 - 12 = 8

b) -4-{-2+3+[-2-(6-9-3)]}

-4 - (-2 + 3 + (-2 + 6))

-4 - (1 + 4) = -4 - 5 = -9

c) [-19-(8-6+15)-3]-[15+(13-10+5)-2]

(-19 - 17 - 3) - (15 + 8 - 2)

-39 - 21 = -60
