Soluzione - Long subtraction
74
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 1 | 4 | 6 | |
| - | 7 | 2 | |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
6-2=4
| Place value | hundreds | tens | ones |
| 1 | 4 | 6 | |
| - | 7 | 2 | |
| 4 |
Because the upper digit (4) 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 (14).
| Place value | hundreds | tens | ones |
| 0 | 14 | ||
| 1 | 4 | 6 | |
| - | 7 | 2 | |
| 4 |
Subtract the numbers in the tens column from the top number:
14-7=7
| Place value | hundreds | tens | ones |
| 0 | 14 | ||
| 1 | 4 | 6 | |
| - | 7 | 2 | |
| 7 | 4 |
Write 0 in the hundreds place.
| Place value | hundreds | tens | ones |
| 0 | 14 | ||
| 1 | 4 | 6 | |
| - | 7 | 2 | |
| 0 | 7 | 4 |
The solution is: 74
