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)

Since there are no grouping symbols and powers,

First operation is Evaluate the expressions within the parentheses.

$\"\"$ (Evaluate powers: $\"\"$ )

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

Next operation is multiplication.

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

Next operation is addition.

= 20 (Add: $\"\"$ ) $\"\"$

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