Soluzione - Long subtraction
268
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 9 | 2 | 6 | |
| - | 6 | 5 | 8 |
2. Subtract the numbers using long subtraction method
Because the upper digit (6) in the ones column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (16).
| Place value | hundreds | tens | ones |
| 1 | 16 | ||
| 9 | 2 | 6 | |
| - | 6 | 5 | 8 |
Subtract the numbers in the ones column from the top number:
16-8=8
| Place value | hundreds | tens | ones |
| 1 | 16 | ||
| 9 | 2 | 6 | |
| - | 6 | 5 | 8 |
| 8 |
Because the upper digit (1) in the tens column is too small to get a positive difference, borrow 1 from the digit (9) in the next number place which becomes (8) and get (11).
| Place value | hundreds | tens | ones |
| 8 | 11 | ||
| 1 | 16 | ||
| 9 | 2 | 6 | |
| - | 6 | 5 | 8 |
| 8 |
Subtract the numbers in the tens column from the top number:
11-5=6
| Place value | hundreds | tens | ones |
| 8 | 11 | ||
| 1 | 16 | ||
| 9 | 2 | 6 | |
| - | 6 | 5 | 8 |
| 6 | 8 |
Subtract the numbers in the hundreds column from the top number:
8-6=2
| Place value | hundreds | tens | ones |
| 8 | 11 | ||
| 1 | 16 | ||
| 9 | 2 | 6 | |
| - | 6 | 5 | 8 |
| 2 | 6 | 8 |
The solution is: 268
