Soluzione - Long subtraction
289
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 3 | 5 | 6 | |
| - | 6 | 7 | |
2. Subtract the numbers using long subtraction method
Because the upper digit (6) in the ones column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (16).
| Place value | hundreds | tens | ones |
| 4 | 16 | ||
| 3 | 5 | 6 | |
| - | 6 | 7 | |
Subtract the numbers in the ones column from the top number:
16-7=9
| Place value | hundreds | tens | ones |
| 4 | 16 | ||
| 3 | 5 | 6 | |
| - | 6 | 7 | |
| 9 |
Because the upper digit (4) in the tens 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 | ||
| 4 | 16 | ||
| 3 | 5 | 6 | |
| - | 6 | 7 | |
| 9 |
Subtract the numbers in the tens column from the top number:
14-6=8
| Place value | hundreds | tens | ones |
| 2 | 14 | ||
| 4 | 16 | ||
| 3 | 5 | 6 | |
| - | 6 | 7 | |
| 8 | 9 |
Write 2 in the hundreds place.
| Place value | hundreds | tens | ones |
| 2 | 14 | ||
| 4 | 16 | ||
| 3 | 5 | 6 | |
| - | 6 | 7 | |
| 2 | 8 | 9 |
The solution is: 289
