📝 Explanation:
Since this worksheet specifies
"Without Regrouping", it means that in each column (ones, tens, hundreds), the top digit is
greater than or equal to the bottom digit. So we can subtract digit by digit without borrowing.
For example, in
257 - 132, we don’t need to borrow because:
- 7 ≥ 2 → 7 - 2 = 5
- 5 ≥ 3 → 5 - 3 = 2
- 2 ≥ 1 → 2 - 1 = 1
This makes the process straightforward and ideal for building confidence in subtraction!
