Question

d) (+10) + (-10) + (+17) + (-10) + (-17)
e) (-6) + (+1) + (+1) + (+5) + (+6)
f) (-3) + (-2) + (+3) + (−8) + (+2) + (+8)

Answer 1

Resposta:

$\sf{segue \: abaixo \: a \: resposta}$

Explicação passo-a-passo:

d)

$\sf{ (+10) + (-10) + (+17) + (-10) + (-17)}$

$\sf{10 + ( - 10) = 0}$

$\sf{17 + ( - 10) + ( - 17)}$

$\sf{17 + ( - 17) = 0}$

$\boxed{\boxed{{\sf{ - 10}}}}$

e)

$\sf{(-6) + (+1) + (+1) + (+5) + (+6)}$

$\sf{( - 6) + 6 = 0}$

$\sf{1 + 1 + 5 = }$

$\boxed{\boxed{{\sf{7}}}}$

f)

$\sf{(-3) + (-2) + (+3) + (−8) + (+2) + (+8)}$

$\sf{( - 3) + 3 = 0}$

$\sf{0 + ( - 2) + ( - 8) + 2 + 8}$

$\sf{( - 2) + 2 = 0}$

$\sf{0 + 0 + ( - 8) + 8}$

$\sf{( - 8) + 8 = 0}$

$\sf{0 + 0 + 0 = }$

$\boxed{\boxed{{\sf{0}}}}$
