Subtraction with Borrowing 🛠️
Sometimes, the top digit is smaller than the bottom digit. In such cases, we borrow from the next column.
Example: Subtract 32 - 17:
- Borrow 1 from the tens place, making the 2 in the ones place a 12.
- Now subtract:
12 - 7 = 5. - In the tens column, subtract:
2 - 1 = 1. - Answer:
32 - 17 = 15.
