Evaluating Algebraic Expressions
Order of Operations/
P.E.M.D.A.S.
Exercise 3

Do not worry about
your difficulties in Mathematics.
I assure you mine are greater.

Albert Einstein,
1879 - 1955, Swiss-American


 

First exercise
You only do the math! (requires Flash)

Second exercise
Now you choose the order
but we'll do the math! (requires Flash)

Evaluating algebraic expressions can be a simple process,
but needs to follow an order of operations to get the right answer. 
The sequence details the order you follow to 
add, subtract, multiply, and divide.  The order is:

P.E.M.D.A.S.
Parenthesis | Exponents | Multiplication | Division | Addition | Subtraction

  1. Perform the operations inside a parenthesis first
  2. Then exponents
  3. Then multiplication and division, from left to right
  4. Then addition and subtraction, from left to right
  5. You can also create a little phrase to memorize the sequence:
    Please Excuse My Dear Aunt Sally
