Subtraction with Regrouping

Subtraction with regrouping is a method used to subtract numbers when the top digit is smaller than the bottom digit in any column, requiring us to borrow from the next column.

To borrow in subtraction, you take 1 from the next left column, which increases the current column by 10.

The first step is to look at the ones place: 2 (from 842) is less than 3 (from 593), so we need to borrow.

After borrowing, you subtract the numbers in the column, adjusting for the borrowed value.
