Soluzione - Long subtraction
808
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 8 | 3 | 2 | |
| 5 | |||
| - | 1 | 9 | |
2. Subtract the numbers using long subtraction method
Because the upper digit (2) in the ones column is too small to get a positive difference, borrow 2 from the digit (3) in the next number place which becomes (1) and get (22).
| Place value | hundreds | tens | ones |
| 1 | 22 | ||
| 8 | 3 | 2 | |
| 5 | |||
| - | 1 | 9 | |
Subtract the numbers in the ones column from the top number:
22-5-9=8
| Place value | hundreds | tens | ones |
| 1 | 22 | ||
| 8 | 3 | 2 | |
| 5 | |||
| - | 1 | 9 | |
| 8 |
Subtract the numbers in the tens column from the top number:
1-1=0
| Place value | hundreds | tens | ones |
| 1 | 22 | ||
| 8 | 3 | 2 | |
| 5 | |||
| - | 1 | 9 | |
| 0 | 8 |
Write 8 in the hundreds place.
| Place value | hundreds | tens | ones |
| 1 | 22 | ||
| 8 | 3 | 2 | |
| 5 | |||
| - | 1 | 9 | |
| 8 | 0 | 8 |
The solution is: 808
