Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 5 | 6 | , | 0 | 8 | ||
| - | 2 | 3 | , | 0 | 2 | 9 |
| , |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 5 | 6 | , | 0 | 8 | 0 | |
| - | 2 | 3 | , | 0 | 2 | 9 |

2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the thousandths column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (10).
