Question

What is the last operation to be performed when finding the value of this expression?

Answer 1

To find out the last operation, we must solve the entire problem.

We are given:

$\frac{5+(-8)}{-3+(-9)(-6)}$

Let's simplify the signs so they don't clutter our equation.

$\frac{5-8}{-3+(-9)(-6)}$

We always need to be sure to use PEMDAS. Since there is no expression to solve in parenthesis and no exponents are present, we will move on to multiplication. We can multiply -9 and -6 in the denominator. When we do that, we get:

$\frac{5-8}{-3+54}$

Next, all you need to do is combine like terms in the numerator and the denominator.

$\frac{-3}{51}$

Simplify.

$-\frac{1}{17}$

To answer the question, the last operation to be performed when finding the value would be division.
