Explicação passo-a-passo:

a)+ 8 + 6 - 20 =

+14 - 20 =

a) -6

b) – ( – 9 ) + ( – 7 ) + (– 3 ) =

+ 9 -7 -3 =

+ 2 - 3 =

-1

c) – ( – 7 ) – ( + 3 ) – 4 =

+ 7 - 3 – 4 =

+ 4– 4 =

c) 0

d) 5 – ( + 7 + 1 ) + (– 4 – 2 ) =

5 – (+ 8)+(– 6 ) =

5- 8 -6 =

-3 -6 =

D) -9

e) – 3 + [ + 1 – ( + 4 – 1 ) + 1 ] =

– 3 + [ + 1 – 3 + 1 ] =

– 3 - 1 =

e) -4

f) + 10 – {– 2 + [ 1 + ( + 4 ) – 8 ] } =

+ 10 – {– 2 + [ 1 + 4– 8 ] } =

+ 10 – {– 2 - 3 } =

+ 10 +5 =

f) +15
