Solve: (400÷(-5)-[-2(93-61)])÷4 | Order of Operations Challenge

Solve the following equation:

$\frac{400\colon(-5)-\lbrack-2(93-61)\rbrack}{4}=$

We begin by addressing the numerator of the fraction.

First we solve the division exercise and the exercise within the parentheses:

$400:(-5)=-80$

$(93-61)=32$

We obtain the following:

$\frac{-80-(-2\times32)}{4}=$

We then solve the parentheses in the numerator of the fraction:

$\frac{-80-(-64)}{4}=$

Let's remember that a negative times a negative equals a positive:

$\frac{-80+64}{4}=$

$\frac{-16}{4}=-4$
