ORDER OF OPERATIONS
MATH 7

ORDER OF OPERATIONS
Do the problem 8 + 4 x (-2) What answers did you come up
with?
Which one is correct and why? Try (-9 + 7) x 9 + 3

PEMDAS
In mathematics, there is a special order that you must follow when doing a problem with many operations.
Parenthesis (or other grouping symbols) Exponents Multiplication Division Addition Subtraction

PEMDAS
Something to help us remember the order: Please Excuse My Dear Aunt Sally
Could also use PEMDAS to remember

Important Information
Grouping Symbols: Parenthesis, absolute value symbols,
“fraction bar division”, and any other type of brackets
These symbols are treated like parenthesis, meaning that the things inside must be done first.

Other Important Information
If you ever have a problem in which only addition and subtraction are left to do, you must work from left to right.
The same goes for multiplication and division.

Examples
12 – 6 x 2 = 18(24 + 36) = 64 - (-5) + 37 x 2 = 16+4
5 32 x 2 – (-8 – 4)2 =

Properties/Homework
The worksheet that I handed out to you has several properties on it that need to be memorized. You will be quizzed on these eventually. Make sure you know them.
Homework is to memorize the properties and worksheet on order of operations.
