If you are trying to solve the problem 6+3x4 where do you start? Fortunatly the rules for the order of operations have been around for hundreds of years to help eliminate the guesswork. A very common method to remember the correct order of operations is PEMDAS, which most people remember by using the expression:
P = Parentheses
E= Exponents
M= Multiplication
D= Division
A= Addition
S=Subtraction
Always work Multiplication, Division, Addition,and Subtraction from Left to Right
Here are two examples of order of operations.

Definition of Order of Operations
Step 1. Parentheses in this example (3+1)=4
Step 2. Exponents 4 squared is 16
Step 3. Multiplication 5 x 16=80
Step 3. Division 8 divided by 4 =2
Remember you read left to right so the division is before the multiplication
Step 2. Exponents 9 squared = 81
Step 1. Parentheses in this example (6+3) = 9
Step 4. Multiplication 2x3=6 and finally subtraction 81-6=75
