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 t = 11, r = 3)

Simplify the expression using order of operations (PEMDAS)

Since there are no grouping symbols and powers.

First operation is evaluating the powers.

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

Next operation is Multiplication.

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

Next operation is Addition.

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

The value of the expression is 394.
