Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 0 | 6 | 3 | 5 | 3 | |
| - | 9 | 6 | 3 | |||
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
3-3=0
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 0 | 6 | 3 | 5 | 3 | |
| - | 9 | 6 | 3 | |||
| 0 |
Because the upper digit (5) in the tens column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (15).
