## How do you show borrowing in subtraction?

Always begin subtracting from ones place.

- Firstly, borrow 10 from tens place to ones place.
- Now, begin the subtraction.
- In ones place, subtract 6 from 13. 13 – 6 = 7.
- In tens place, after lending 10 to ones place, it is left with 5. Now, subtract 5 from 5. 5 – 5 = 0.
- Hence, 63 – 56 = 7.
