Order of Operations:

To simplify the expression follow the order of operations: (PEMDAS)

1.      Evaluate the expressions inside the Parenthesis/Brackets (P).

2.      Evaluate Powers/Exponents (E).

3.      Multiply and/or Divide in order from left to right (MD).

4.      Add and/or Subtract in order from left to right (AS).

A simple technique for remembering the order of operations is turned into phrase "Please Excuse My Dear Aunty Sally"

The expression is .

Write the expression as division problem .

         (Substitutive the value of x = 3 and y = 4)

First operation is evaluating the expression within the parenthesis.

                    (Multiply: )

                             (Subtract: )

Next operation is division.

= 13                                    (Divide: )

The value of given expression is 13.
