When there is more than one operation involved in a mathematical problem, it must be solved by using the correct order of operations. A number of teachers use acronyms with their students to help them to retain the order. The 2 most common acronyms are:
PLEASE EXCUSE MY DEAR AUNT SALLY or just P.E.M.D.A.S.
Parentheses-Exponents-Multiplication-Division-Addition-Subtraction
Rules
Remember, calculators will perform operations in the order which you enter them, therefore, you will need to enter the operations in the correct order for the calculator to give you the right answer.

Rules
- Calculations must be done from left to right within an operation.
- Calculations in parenthesis are done first. When you have more than one set of brackets, do the inner brackets first.
- Exponents (or radicals) must be done next.
- Multiply and divide in the order the operations occur.*
- Add and subtract in the order the operations occur.*
Remember, calculators will perform operations in the order which you enter them, therefore, you will need to enter the operations in the correct order for the calculator to give you the right answer.
