Soluzione - Long subtraction
782
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 9 | 3 | 2 | |
| - | 1 | 5 | 0 |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
2-0=2
| Place value | hundreds | tens | ones |
| 9 | 3 | 2 | |
| - | 1 | 5 | 0 |
| 2 |
Because the upper digit (3) in the tens column is too small to get a positive difference, borrow 1 from the digit (9) in the next number place which becomes (8) and get (13).
| Place value | hundreds | tens | ones |
| 8 | 13 | ||
| 9 | 3 | 2 | |
| - | 1 | 5 | 0 |
| 2 |
Subtract the numbers in the tens column from the top number:
13-5=8
| Place value | hundreds | tens | ones |
| 8 | 13 | ||
| 9 | 3 | 2 | |
| - | 1 | 5 | 0 |
| 8 | 2 |
Subtract the numbers in the hundreds column from the top number:
8-1=7
| Place value | hundreds | tens | ones |
| 8 | 13 | ||
| 9 | 3 | 2 | |
| - | 1 | 5 | 0 |
| 7 | 8 | 2 |
The solution is: 782
