Soluzione - Long subtraction
238
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 3 | 0 | 0 | |
| - | 6 | 2 | |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ones column is too small to get a positive difference, borrow 1 from the number to the left (30) which becomes (29) and get (10).
| Place value | hundreds | tens | ones |
| 2 | 9 | 10 | |
| 3 | 0 | 0 | |
| - | 6 | 2 | |
Subtract the numbers in the ones column from the top number:
10-2=8
| Place value | hundreds | tens | ones |
| 2 | 9 | 10 | |
| 3 | 0 | 0 | |
| - | 6 | 2 | |
| 8 |
Subtract the numbers in the tens column from the top number:
9-6=3
| Place value | hundreds | tens | ones |
| 2 | 9 | 10 | |
| 3 | 0 | 0 | |
| - | 6 | 2 | |
| 3 | 8 |
Write 2 in the hundreds place.
| Place value | hundreds | tens | ones |
| 2 | 9 | 10 | |
| 3 | 0 | 0 | |
| - | 6 | 2 | |
| 2 | 3 | 8 |
The solution is: 238
