Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 9 | 8 | 0 | 1 | 3 | 5 | |
| 7 | 1 | 0 | ||||
| - | 7 | 3 | ||||
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
5-0-3=2
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 9 | 8 | 0 | 1 | 3 | 5 | |
| 7 | 1 | 0 | ||||
| - | 7 | 3 | ||||
| 2 |
Because the upper digit (3) in the tens column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (13).
