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)

 

This calculator does not handle exponents at this time.

=

Enter a math expression (with +, -, *, and / signs).  Try to calculate the solution, mentally before clicking .

Others prefer: 

Please

Excuse

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)

or

(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.
