The order of operations is a set of rules that describe the order in which math operations are done. Try doing this math problem:

7+ 3×2
If your answer was 20, you are incorrect!
The correct way to do this problem is to follow the order of operations, which says to multiply before adding. The correct answer is 13!

General Order of Operations
1. Parentheses
2. Exponents
3. Multiplication and Division (left to right)
4. Addition and Subtraction (left to right)

Example 1: Evaluate 2 - 9 + 32 + 4 X 1
2 - 9 + 9 + 4 X 1
2 - 1 + 4 X 1
2 - 1 + 4
1 + 4
5

Example 2: Evaluate 10 + 2+ 3 2 - 1 X 2 + (6 - 1)
10 + 2 3 + 2 - 1 X 2 + 5
10 + 8 2 - 1 X 2 + 5
10 + 4 - 1 X 2 + 5
10 + 4 - 2 + 5
14 - 2 + 5
12 + 5
