Order of Operations:

To simplify the expression follow the order of operations: (PEMDAS).

1. Evaluate the expressions inside the Parenthesis/Brackets (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". $\"\"$

The expression is $\"\"$

$\"\"$ (Substitute $\"\"$ )

Simplify the expression using order of operations (PEMDAS)

First operation is evaluate the expressions inside the brackets.

$\"\"$ (Multiply: $\"\"$ )

$\"\"$ (Add: $\"\"$ )

Next operation is Division.

$\"\"$ (Divide: $\"\"$ )

$\"\"$

The value of the expression is 7.
