762
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 9 | 5 | 0 | |
| - | 1 | 8 | 8 |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ones column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (10).
| Place value | hundreds | tens | ones |
| 4 | 10 | ||
| 9 | 5 | 0 | |
| - | 1 | 8 | 8 |
Subtract the numbers in the ones column from the top number:
10-8=2
| Place value | hundreds | tens | ones |
| 4 | 10 | ||
| 9 | 5 | 0 | |
| - | 1 | 8 | 8 |
| 2 |
Because the upper digit (4) 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 (14).
| Place value | hundreds | tens | ones |
| 8 | 14 | ||
| 4 | 10 | ||
| 9 | 5 | 0 | |
| - | 1 | 8 | 8 |
| 2 |
Subtract the numbers in the tens column from the top number:
14-8=6
| Place value | hundreds | tens | ones |
| 8 | 14 | ||
| 4 | 10 | ||
| 9 | 5 | 0 | |
| - | 1 | 8 | 8 |
| 6 | 2 |
Subtract the numbers in the hundreds column from the top number:
8-1=7
| Place value | hundreds | tens | ones |
| 8 | 14 | ||
| 4 | 10 | ||
| 9 | 5 | 0 | |
| - | 1 | 8 | 8 |
| 7 | 6 | 2 |
The solution is: 762
