Learning Objective
I can subtract two-digit numbers with regrouping.
- 1
When subtracting, if the top digit is smaller than the bottom digit in the same place, you need to regroup.
- 2
To regroup, you take one from the tens place and add ten to the ones place.
- 3
Regrouping helps you subtract by changing how a number is represented without changing its total value.
