Alguém me ajuda

Calcule:
a) – 8 – ( 2 + 3) =
b) – 20 – ( 5 – 1 ) =
c) – 16 – 9 – ( 4 + 3) – ( -12 + 7) =
d) ( - 3 + 6 – 11) – ( - 1 2 – 15 + 16) + ( 17 – 20 + 3) =
e) – (- 8 + 1) – ( - 9 – 3) =
f) ( -1 – 2 – 3) – ( +7 -6 +8) =
g) (-5 + 3 – 10) – ( -16 + 8 - 9) =

Answer 1

Explicação passo-a-passo:

a) – 8 – ( 2 + 3) = - 8 - 2 - 3 = -13

b) – 20 – ( 5 – 1 ) = - 20 - 5 + 1 = -25

c) – 16 – 9 – ( 4 + 3) – ( -12 + 7) =

- 16 - 9 - 4 - 3 + 12 - 7 = -27

d) ( - 3 + 6 – 11) – ( - 1 2 – 15 + 16) + ( 17 – 20 + 3) =

- 3 + 6 - 11 + 12 - 16 + 17 - 20 + 3 = -12

e) – (- 8 + 1) – ( - 9 – 3) = +8 - 1 + 9 + 3 = 19

f) ( -1 – 2 – 3) – ( +7 -6 +8) = - 1 - 2 - 3 - 7 + 6 - 8 = -15

g) (-5 + 3 – 10) – ( -16 + 8 - 9) =

- 5 + 3 - 10 + 16 - 8 + 9 = 5
