Question

6. Calcule

a) −5− 3 ∙ (−2)
d) 2+ 5 ∙ (−3)− (−4)
b) |−11|
e) −11 − 2 ∙ (−3)+ 3
c) |7 − 4| +|4 −7|
f) −8 + 3 ∙ [2− (−1)]

Answer 1

Explicação passo-a-passo:

a)-5-3.(-2)

-5-6=11

d)2+5.(-3)-(-4)=

2+(-15)-(-4)=

2+(-19)=-17

b)11

e)-11-2.(-3)+3

-11-6+3=

17+3=20

c)|7-4|+|4-7|

3+(-3)=0

f)-8+3 . [2-(-1)]

-8+3 . 3=

-8+9=1
