Soluzione - Long subtraction
37
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 1 | 3 | 4 | |
| 6 | 3 | ||
| - | 3 | 4 | |
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 (3) in the next number place which becomes (2) and get (14).
| Place value | hundreds | tens | ones |
| 2 | 14 | ||
| 1 | 3 | 4 | |
| 6 | 3 | ||
| - | 3 | 4 | |
Subtract the numbers in the ones column from the top number:
14-3-4=7
| Place value | hundreds | tens | ones |
| 2 | 14 | ||
| 1 | 3 | 4 | |
| 6 | 3 | ||
| - | 3 | 4 | |
| 7 |
Because the upper digit (2) 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 (12).
| Place value | hundreds | tens | ones |
| 0 | 12 | ||
| 2 | 14 | ||
| 1 | 3 | 4 | |
| 6 | 3 | ||
| - | 3 | 4 | |
| 7 |
Subtract the numbers in the tens column from the top number:
12-6-3=3
| Place value | hundreds | tens | ones |
| 0 | 12 | ||
| 2 | 14 | ||
| 1 | 3 | 4 | |
| 6 | 3 | ||
| - | 3 | 4 | |
| 3 | 7 |
Write 0 in the hundreds place.
| Place value | hundreds | tens | ones |
| 0 | 12 | ||
| 2 | 14 | ||
| 1 | 3 | 4 | |
| 6 | 3 | ||
| - | 3 | 4 | |
| 0 | 3 | 7 |
The solution is: 37
