Key Concept

Order of operations (PEMDAS)

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”

$\"\"$

The expression is $\"\"$ .

$\"\"$ (Substitute: a = $\"\"$ , b = $\"\"$ 3 and c = 0.5) $\"\"$

In the given expression there are no grouping symbols.

First operation is multiplication.

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

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

Next operation is multiplication.

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

Next operation is division.

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

$\"\"$

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