1 Order of Operations

2 Definition The order in which mathematicians perform math problems. a)Parenthesis – working inward outward b)Exponents c)Multiply or Divide – Left to Right d)Add or Subtract – Left to Right

3 Mnemonic P lease Parenthesis E xcuse Exponents M y D ear Multiply or Divide – Left to Right A unt S ally Add or Subtract – Left to Right

4 Example 1: 2 x 3 - (4-2) Multiplication Parenthesis Subtraction Addition Exponents

5 2 x 3 - (4-2) x Parenthesis Exponents Multiply 2 x Add or Subtract – Left to Right

6 Example 2: 4 X 6 – (3 + 4) Multiplication Parenthesis Subtraction Addition Exponents

7 4 X 6 – (3 + 4) x Parenthesis Exponents 24 – Multiply 4 X 6 – Add or Subtract – Left to Right
