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”

In the given expression there are grouping symbols.

First operation is Evaluate the expressions Parenthesis.

                    (Divide: ) \ \

                          (Additive inverse property: )

Next operation is Multiplication

                                      (Zero product property: ) \ \

                                             (Multiplicative inverse property: )

The value of the expression is 1.
