Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 1 | 4 | 3 | 2 | 7 | ||||||
| - | 2 | , | 6 | 3 | 8 | 2 | ||||
| , |
Put zeros in the blank number places:
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 1 | 4 | 3 | 2 | 7 | , | 0 | 0 | 0 | 0 | |
| - | 2 | , | 6 | 3 | 8 | 2 | ||||

2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ten thousandths column is too small to get a positive difference, borrow 1 from the number to the left (7.000) which becomes (6.999) and get (10).
