619
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 6 | 2 | 1 | |
| - | 2 | ||
2. Subtract the numbers using long subtraction method
Because the upper digit (1) in the ones column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (11).
| Place value | hundreds | tens | ones |
| 1 | 11 | ||
| 6 | 2 | 1 | |
| - | 2 | ||
Subtract the numbers in the ones column from the top number:
11-2=9
| Place value | hundreds | tens | ones |
| 1 | 11 | ||
| 6 | 2 | 1 | |
| - | 2 | ||
| 9 |
Write 1 in the tens place.
| Place value | hundreds | tens | ones |
| 1 | 11 | ||
| 6 | 2 | 1 | |
| - | 2 | ||
| 1 | 9 |
Write 6 in the hundreds place.
| Place value | hundreds | tens | ones |
| 1 | 11 | ||
| 6 | 2 | 1 | |
| - | 2 | ||
| 6 | 1 | 9 |
The solution is: 619
