Soluzione - Long subtraction
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 |
| 1 | 0 | 5 | 0 | 3 | 7 | |
| - | 6 | 7 | 3 | 8 | 9 | |
2. Subtract the numbers using long subtraction method
Because the upper digit (7) in the ones 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 (17).
