44
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths |
| 5 | 0 | , | 8 | |
| - | 6 | , | 8 | |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the tenths column from the top number:
8-8=0
| Place value | tens | ones | . | tenths |
| 5 | 0 | , | 8 | |
| - | 6 | , | 8 | |
| , | 0 |
Because the upper digit (0) in the ones 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 (10).
| Place value | tens | ones | . | tenths |
| 4 | 10 | |||
| 5 | 0 | , | 8 | |
| - | 6 | , | 8 | |
| , | 0 |
Subtract the numbers in the ones column from the top number:
10-6=4
| Place value | tens | ones | . | tenths |
| 4 | 10 | |||
| 5 | 0 | , | 8 | |
| - | 6 | , | 8 | |
| 4 | , | 0 |
Write 4 in the tens place.
| Place value | tens | ones | . | tenths |
| 4 | 10 | |||
| 5 | 0 | , | 8 | |
| - | 6 | , | 8 | |
| 4 | 4 | , | 0 |
The solution is: 44
