Learning Objective
I can subtract multi-digit numbers with grouping and regrouping to solve real-world problems.
- 1
Unlike addition, the order of numbers matters in subtraction; you must subtract the number you are taking away from the first number.
- 2
When subtracting multi-digit numbers, always start with the ones place column and work your way to the left.
- 3
When the top digit is smaller than the bottom digit, you need to borrow from the digit to the left, which represents borrowing a 10.
