12.03 Order of Operations

Number Operations

Refresher pp 26-7

Learning Objectives:

The student will:

illustrate and explain the order of operations using paper and pencil or a calculator.

Order of Operations: Some students like these rules:

B	E	DM	AS
Brackets (parentheses)	Exponents	Divide or Multiply	Add or Subtract
(Innermost first)	(Powers or roots)	(from LEFT-to-RIGHT)	(from LEFT-to-RIGHT)

Others prefer:

Please	Excuse	My Dear	Aunt Sally
Parentheses (brackets)	Exponents	Divide or Multiply	Add or Subtract
(Innermost first)	(Powers or roots)	(from LEFT-to-RIGHT)	(from LEFT-to-RIGHT)

When you have more than one operation in a math problem, you must solve it following the correct ORDER OF OPERATIONS:

First, copy the problem EXACTLY.
Then go through each level of operations

(Brackets Exponents Multiply Divide Add Subtact)

(Please Excuse My Dear Aunt Sally)

Do the operations within each level from left-to-right.
Write the answer directly below the operation sign.
Bring down the other numbers (be careful not to re-use any).
Continue until all operations are completed.
