Soluzione - Long subtraction
58
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 1 | 4 | 4 | |
| - | 8 | 6 | |
2. Subtract the numbers using long subtraction method
Because the upper digit (4) in the ones column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (14).
| Place value | hundreds | tens | ones |
| 3 | 14 | ||
| 1 | 4 | 4 | |
| - | 8 | 6 | |
Subtract the numbers in the ones column from the top number:
14-6=8
| Place value | hundreds | tens | ones |
| 3 | 14 | ||
| 1 | 4 | 4 | |
| - | 8 | 6 | |
| 8 |
Because the upper digit (3) in the tens column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (13).
| Place value | hundreds | tens | ones |
| 0 | 13 | ||
| 3 | 14 | ||
| 1 | 4 | 4 | |
| - | 8 | 6 | |
| 8 |
Subtract the numbers in the tens column from the top number:
13-8=5
| Place value | hundreds | tens | ones |
| 0 | 13 | ||
| 3 | 14 | ||
| 1 | 4 | 4 | |
| - | 8 | 6 | |
| 5 | 8 |
Write 0 in the hundreds place.
| Place value | hundreds | tens | ones |
| 0 | 13 | ||
| 3 | 14 | ||
| 1 | 4 | 4 | |
| - | 8 | 6 | |
| 0 | 5 | 8 |
The solution is: 58
