How can the order of operations be used to simplify expressions?
Lapatulllka [165]
Order of Operations, also known as PEMDAS (Parentheses, Exponents, Multiplication & Division, Addition & Subtraction), can help to simplify an equation by guiding you through the steps to solve it.

This is because it tells you to solve the parentheses. If there is none, but you've already done this, you solve for exponents, etc. 

The progressive soling of the equation not only makes it physically shorter, but also brings you closer to the answer.

Hope this helps, and I was the brainliest! :)

Decrease of 25% means only 855 people? Okay, so you want to backtrack. If you divide by 25% you’re going to get what it was for a 75% decrease. So divide by .75 instead. 855/.75 = 1140 unemployed residents last month
