Answer:

When you use the order of operations, there is a certain set of rules you must follow or you can possibly get the wrong answer. When using the order of operations, PEMDAS (parenthesizes, exponents, multiplication, division, addition, and subtraction), in order to avoid mistakes, you must follow in that order.

Explanation:

For example:


7^(2) + (8+8) - 12\\\\*PEMDAS*\\\\7^(2) + 16 -12\\\\49 + 16 - 12 \\\\\65 - 12\\\\53\\\\

First, we solve any operations inside of parentheses or brackets. Second, we solve any exponents. Third, we solve all multiplication and division from left to right. Fourth, we solve all addition and subtraction from left to right.
