Summary The Order of Operations is the order in which you solve a problem. This process is very easy to use if you use the word PEMDAS.
How To Order of Operations is pretty simple if you follow the method "PEMDAS." PEMDAS is short for... Perentheses
Exponents
Multiplication/Division
Addition/Subtraction This is the way to follow through with your Order of Operation questions.

Steps:
As a good reminder you can write the words PEMDAS on your paper. (Optional)
Next, look to see if you have any Perentheses. If there is none then continue on to your next letter on the PEMDAS list.
The letter after is Exponents. Check to see if there are any exponents. If there is any, simplify, and continue on. If there in none, just continue on to the next letter.
After exponents you move on to Addition/Subtraction. Since addition and subtraction are placed together on the list, whichever one comes first out of the two of them is the one that you do first.
The same thing follows for Multiplication/ Division. Whichever one comes first is the one you solve first.
Example: P
E
MD
AS 1 + 2 - (3 x 4) x 3
1 + 2 - 12 x 3 1 + 2 - 36 3 - 36 33
Easy Problems
3+4×1=7
5+6-7+(5-1)=? Answer: 0 10+9-7 Answer is 12
Medium Problems
16÷4×(4+9)=12
7x3(2+1)-11=? Answer: 52 36 ÷ 4 + 9 × 7 Answer is 72 Hard Problems
