Soluzione - Long subtraction
1,8
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths |
| 3 | , | 2 | |
| 0 | , | 4 | |
| - | 1 | ||
| , |
Put zeros in the blank number places:
| Place value | ones | . | tenths |
| 3 | , | 2 | |
| 0 | , | 4 | |
| - | 1 | , | 0 |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (2) in the tenths column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (12).
| Place value | ones | . | tenths |
| 2 | 12 | ||
| 3 | , | 2 | |
| 0 | , | 4 | |
| - | 1 | , | 0 |
| , |
Subtract the numbers in the tenths column from the top number:
12-4-0=8
| Place value | ones | . | tenths |
| 2 | 12 | ||
| 3 | , | 2 | |
| 0 | , | 4 | |
| - | 1 | , | 0 |
| , | 8 |
Subtract the numbers in the ones column from the top number:
2-0-1=1
| Place value | ones | . | tenths |
| 2 | 12 | ||
| 3 | , | 2 | |
| 0 | , | 4 | |
| - | 1 | , | 0 |
| 1 | , | 8 |
The solution is: 1,8
