Soluzione - Long subtraction
560
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 8 | 4 | 8 | |
| - | 2 | 8 | 8 |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
8-8=0
| Place value | hundreds | tens | ones |
| 8 | 4 | 8 | |
| - | 2 | 8 | 8 |
| 0 |
Because the upper digit (4) in the tens column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (14).
| Place value | hundreds | tens | ones |
| 7 | 14 | ||
| 8 | 4 | 8 | |
| - | 2 | 8 | 8 |
| 0 |
Subtract the numbers in the tens column from the top number:
14-8=6
| Place value | hundreds | tens | ones |
| 7 | 14 | ||
| 8 | 4 | 8 | |
| - | 2 | 8 | 8 |
| 6 | 0 |
Subtract the numbers in the hundreds column from the top number:
7-2=5
| Place value | hundreds | tens | ones |
| 7 | 14 | ||
| 8 | 4 | 8 | |
| - | 2 | 8 | 8 |
| 5 | 6 | 0 |
The solution is: 560
