Question

resolva:

[+(32).(-4)]-[-(-8)÷(+2)]


b) {[(+52/2) +(-81)-[-13×(-31]}​

Answer 1

a)

$32 \times ( - 4) - ( - ( - 8) \div 2)$

$32 \times ( - 4) - (4)$

$( - 128) - 4 = - 132$

b)

$( \frac{52}{2} ) + ( - 81) - ( - 13 \times ( - 31))$

$( \frac{52}{2} ) + ( - 81) - ( - 403)$

$26 - 81 + 403 = 348$

Creio que seja isso
