THE ORDER OF OPERATIONS


You need to remember the order in which arithmetic operations must be performed. PEMDAS (or Please Excuse My Dear Aunt
Sally) may help you remember the order.


REMEMBER PEMDAS


When performing multiple operations, remember PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition
and Subtraction. You may find it easier to remember as Please Excuse My Dear Aunt Sally.

Please = Parentheses
Excuse = Exponents
My Dear = Multiplication and Division (from left to right)
Aunt Sally = Addition and Subtraction (from left to right)
