About Order of Operations:
The order of operations tells us which operation to perform in which order when faced with a problem that contains more than one operation. The order of operations:
- Parentheses
- Exponents
- Multiply/Divide - working from left to right
- Add/Subtract - working from left to right
Test Objectives
- Demonstrate a memorization of the order of operations
- Demonstrate the ability to correctly understand the order in PEMDAS
- Demonstrate the ability to correctly evaluate a problem with multiple operations
