Question

3) Resolva:

a) – 20 – [ 41 – (18 – 10) +11] =

b) 15 – [-12 +(- 19 – 15) – 21 =

c) 22 – { 10 – [ 29 – 10] – 70} =

d) 33 – { -26 – [12 – (- 35 – 41) – 80] -36} =

Answer 1

Explicação passo-a-passo:

a) – 20 – [ 41 – (18 – 10) +11] =

-20-[41-(8)+11]=

-20-[41-8+11]=

-20-[33+11]=

-20-[44]=

-20-44=

-64

b) 15 – [-12 +(- 19 – 15) – 21 =

15-[-12+(-34)-21=

15-[-46-21]=

15-[-67]=

82

c) 22 – { 10 – [ 29 – 10] – 70} =

22-{10-[19]-70}=

22-{10-19-70}=

22-{-9-70}=

22-{-79}=

101

d) 33 – { -26 – [12 – (- 35 – 41) – 80] -36} =

33-{-26-[12-(-76)-80]-36}=

33-{-26-[88-80]-36}=

33-{-26-[8]-36}=

33-{-26-8-16}=

33-{-34-16}=

33-{-50}=

83
