Detailed performance analysis
Definition: Expanded notation is a way of writing numbers to show the value of each digit by expressing each digit multiplied by its place value.
- Place Value System: Each position in a number represents a power of 10
- Standard Form: Normal way of writing numbers (e.g., 3,456)
- Expanded Form: Shows value of each digit (e.g., 3,000 + 400 + 50 + 6)
- Word Form: Numbers written in words (e.g., three thousand four hundred fifty-six)
Place Value: The value of a digit based on its position in a number
