Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 9 | , | 4 | 2 | 8 | |
| - | 4 | , | 9 | 3 | 1 | |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
8-1=7
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 9 | , | 4 | 2 | 8 | |
| - | 4 | , | 9 | 3 | 1 | |
| , | 7 |
Because the upper digit (2) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (12).
