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 Powers

$\"\"$ (Evaluate the power: $\"\"$ )

Next operation is Subtraction.
