Order of Operations

Objective & Essential Question  Common Core Objective: 6.EE.1  Student Friendly Terms: Students will be able to perform basic five and six step order of operations problems with 80% accuracy.  Essential Question: Why is order important in math?

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

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

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

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

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

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