Soluzione - Long subtraction
67
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones |
| 7 | 2 | |
| - | 5 | |
2. Subtract the numbers using long subtraction method
Because the upper digit (2) in the ones column is too small to get a positive difference, borrow 1 from the digit (7) in the next number place which becomes (6) and get (12).
| Place value | tens | ones |
| 6 | 12 | |
| 7 | 2 | |
| - | 5 | |
Subtract the numbers in the ones column from the top number:
12-5=7
| Place value | tens | ones |
| 6 | 12 | |
| 7 | 2 | |
| - | 5 | |
| 7 |
Write 6 in the tens place.
| Place value | tens | ones |
| 6 | 12 | |
| 7 | 2 | |
| - | 5 | |
| 6 | 7 |
The solution is: 67
