Question

quanto e 2-{-3×[2+8×(-2-7)÷(-6)]-10}

Answer 1

-2 - 7 = -5
2 + 8 = 10
10 ÷ 5 = -2
-2 - 6= -4
-4 x (-4) = -16
-16 - 10 = -6
2 - 6= -4

Resultado: -4

Answer 2

Resposta:

2 – {(–3) × [2 + 8 × (–2 – 7) ÷ (–6)] – 10}.

2 – {(–3) × [2 + 8 × -5 ÷ (–6)] – 10}.

2 – {(–3) × [10 × -5 ÷ (–6)] – 10}.

2 – {(–3) × [-2 ÷ –6] – 10}.

2 – {–3 × -4 – 10}.

2 – {-12 – 10}.

2 – -2. = 0
