Soluzione - Long subtraction
294
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 5 | 8 | 8 | |
| - | 2 | 9 | 4 |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
8-4=4
| Place value | hundreds | tens | ones |
| 5 | 8 | 8 | |
| - | 2 | 9 | 4 |
| 4 |
Because the upper digit (8) in the tens 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 (18).
| Place value | hundreds | tens | ones |
| 4 | 18 | ||
| 5 | 8 | 8 | |
| - | 2 | 9 | 4 |
| 4 |
Subtract the numbers in the tens column from the top number:
18-9=9
| Place value | hundreds | tens | ones |
| 4 | 18 | ||
| 5 | 8 | 8 | |
| - | 2 | 9 | 4 |
| 9 | 4 |
Subtract the numbers in the hundreds column from the top number:
4-2=2
| Place value | hundreds | tens | ones |
| 4 | 18 | ||
| 5 | 8 | 8 | |
| - | 2 | 9 | 4 |
| 2 | 9 | 4 |
The solution is: 294
