Use the expession is \ \

                        (Substitute ) \ \

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

1.     Evaluate the expressions inside Brackets/Parenthesis (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 pf operations is turned into phrase \ \ “Please Excuse My Dear Aunty Sally”

\ \

First operation is evaluating the expression within the parenthesis.

      (Subtract: ) \ \

        (Cancel commen terms) \ \

Second operation is evaluating powers.

               (Evaluate power: )

Third operation is addition.

                        (Add: )

                              (Product of two same signs is positive)

Fourth operation is addition.

                                 (Add: )
