Soluzione - Long subtraction
10,6
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths |
| 1 | 3 | , | 5 | |
| 0 | , | 3 | ||
| - | 2 | , | 6 | |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (5) 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 (15).
| Place value | tens | ones | . | tenths |
| 2 | 15 | |||
| 1 | 3 | , | 5 | |
| 0 | , | 3 | ||
| - | 2 | , | 6 | |
| , |
Subtract the numbers in the tenths column from the top number:
15-3-6=6
| Place value | tens | ones | . | tenths |
| 2 | 15 | |||
| 1 | 3 | , | 5 | |
| 0 | , | 3 | ||
| - | 2 | , | 6 | |
| , | 6 |
Subtract the numbers in the ones column from the top number:
2-0-2=0
| Place value | tens | ones | . | tenths |
| 2 | 15 | |||
| 1 | 3 | , | 5 | |
| 0 | , | 3 | ||
| - | 2 | , | 6 | |
| 0 | , | 6 |
Write 1 in the tens place.
| Place value | tens | ones | . | tenths |
| 2 | 15 | |||
| 1 | 3 | , | 5 | |
| 0 | , | 3 | ||
| - | 2 | , | 6 | |
| 1 | 0 | , | 6 |
The solution is: 10,6
