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.

          (Evaluate power: )

              (Multiply: )

                         (Additive inverse property: 16 16 = 0)

Next operation is Multiplication.

                             (Multiply: )

Next operation is Addition.

                                        (Add: 0 + 28 = 28)

The expression is .
