The expression is

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 Evaluate the expressions Parenthesis.

                  (Multiply: )

                         (Subtract: )

Next operation is multiplication.

                              (Multiplicative identity property: )

                                     (Multiplicative inverse property: )

Next operation is addition.

                                           (Add: )

The value of the expression is 3.
