Subtraction with regrouping:

Example:

1. Start from ones place 7 minus 2 is 5.
2. In the tens place 3 is less than 8, so 1 is borrowed from 0 which has borrowed 1 from 3. So the result in tens place is 13 minus 8 which is 5.
3. In the hundreds place 0 becomes 9, the result is 3.
4. In thousands place, 3 becomes 2 and the result is 1.
