$\"\"$

The expression is $\"\"$

Substitute the values $\"\"$ above equation

$\"\"$

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 of operations is turned

into phrase.

“Please Excuse My Dear Aunty Sally” $\"\"$

First operation is evaluate the expressions parenthesis

$\"\"$

(Multiply: $\"\"$ )

$\"\"$ (Additive inverse property: $\"\"$ ) $\"\"$

Next operation is Exponents

$\"\"$ (Evaluate power: $\"\"$ ) \ \ Next operation is Subtraction

$\"\"$ (Subtract: $\"\"$ ) $\"\"$

The value of the expression is $\"\"$ .
