Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths | ten millionths | hundred millionths |
| 0 | , | 7 | 5 | |||||||
| - | 0 | , | 6 | 6 | 6 | 6 | 6 | 6 | 6 | 6 |
| , |
Put zeros in the blank number places:
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths | ten millionths | hundred millionths |
| 0 | , | 7 | 5 | 0 | 0 | 0 | 0 | 0 | 0 | |
| - | 0 | , | 6 | 6 | 6 | 6 | 6 | 6 | 6 | 6 |

2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the hundred millionths column is too small to get a positive difference, borrow 1 from the number to the left (500.000) which becomes (499.999) and get (10).
