🔢 What is “Regrouping”?
Regrouping (also called “borrowing”) happens when the top digit in a column is smaller than the bottom digit. You borrow 1 from the next higher place value (e.g., from tens to ones), turning the top digit into a larger number so you can subtract.

## 💡 Tip for Students:
Always start from the
ones place. If the top number is smaller,
regroup (borrow) from the tens place. Remember: borrowing reduces the tens digit by 1 and adds 10 to the ones digit.
