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

The expression is .

      (Substitute )

Apply the order of operations (PEDMAS).

Since there are no parenthesis, first operation is evaluating power.

          (Evaluate power: )

            (Multiply: )

Next operation is addition.

            (Add: )

Next operation is subtraction.

                 (Subtract: )

       (Multiply the numerator and the denominator by 10)

             (Multiply: and )

                 (Divide: )

 The value of the expression is 24.
