Answer 1

Resposta:

Explicação passo-a-passo:

a)-10 (-9)÷(+3)+(-4)×(-3) = 42

b)(-6+5×2 12)×(-10: 5-4-3-1)= 10540

c) 10-(+30)÷(-15)+(+4)×(-1)= 8

d)6+(-4)÷(-2) + (-8)×(+1) )= -4

e)(-15)÷(+3)+(5)×(-2)= -2

2-Resolva

a)(-5+3×2-1)÷(-10÷5-1×4)= 0

b) (5×1-3×2)÷(-3÷3+1×2)= -1

c)(-6÷6+2×5)×(2+1×3-10÷5)= 27

3-Calcule:

a)-7×[-2 +(-1+7-5)] = 7

b)-8-[+3-(5-2+3)]= 24

c)-10-[-10-(-10-10-10)]= -310

4-Resolva as expressões

a){-10×5-[8-(-7+4)×(3×1-5)]} = 100

b) {[(+20)×(-5)+3×(-2+6÷2)]-10÷5}= -99

c) {[15×(-3)+4-3×2]}÷(-7)= 6,71=7

d) 14-{2×[35-(-4+34)]+2}÷2= 8

5-Ache o valor numérico das expressões

a) (-3)²+(-2)³×(+1)= 1

b)-1+(-5)²×(+5)-(-1)= 125
