About PEMDAS:

When we encounter multiple operations in a problem, we use the order of operations to determine which operation takes priority. PEMDAS is an acronym used to remember the order of operations.PEMDAS:

  1. Parentheses
  2. Exponents
  3. Multiply or Divide (working from left to right)
  4. Add or Subtract (working from left to right)


Test Objectives
  • Demonstrate a memorization of the Order of Operations
  • Demonstrate an understanding of how to perform the steps MD and AS in PEMDAS
  • Demonstrate the ability to solve a problem with multiple operations using the Order of Operations
