Tina Hughes-MAT-116 Elrod, the best way that I can explain the order of operations is to show you how it is commonly used in numeric equations.

Always follow these rules: 1. Perform the operations indicated within parenthesis first. 2. Proceeding from left to right, perform the multiplications and division first. 3. Then perform the additions and subtractions also from left to right. Example: We need to find the value of 9 + 12.4 using the “PEMDAS” formula. 9 + 12.4 = 2 + 48 = 50 (NEVER USE “X” to show multiplication. It is best to use a dot (.) to show that you need to multiply) How did we reach this result? 1.
