Question

- 2 + -{-1 + [5 - 3 × (10 + 1) × 3] - 5 × 7}

-5 - [3 × (7 - 5 - 3) - 22 : 11 ]

2- (5 × 10 + 60) -5 × 20 : ( -17 + 13)

3 - { 30 : 5- [ -7 × (5-2) +3] : 6 }

calcule o valor das expressões​

Answer 1

Explicação passo-a-passo:

1) -2+{-1+[5-3×(10+1)×3]-5×7}

-2+{-1+[5-3×11×3]-5×7}

-2+{-1+[5-33×3]-5×7}

-2+{-1+[5-99]-5×7}

-2+{-1+(-94)-5×7}

-2+{-1-94-35}

-2+{-95-35}

-2+(-130)

-2-130

-132

2) -5-[3×(7-5-3)-22÷11]

-5-[3×(2-3)-22÷11]

-5-[3×(-1)-22÷11]

-5-[-3-2]

-5-(-5)

-5+5

0

3) 2-(5×10+60)-5×20÷(-17+13)

2-(50+60)-5×20÷(-4)

2-(+110)-100÷(-4)

2-110+25

-108+25

-83

4) 3-{30÷5-[-7×(5-2)+3]÷6}

3-{30÷5-[-7×3+3]÷6}

3-{30÷5-[-21+3]÷6}

3-{30÷5-(-18)÷6}

3-{30÷5+18÷6}

3-{6+3}

3-9

-6
