Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 3 | , | 4 | 9 | 7 | 6 | |
| - | 1 | , | 5 | 5 | 2 | 2 |

2. Subtract the numbers using long subtraction method
Subtract the numbers in the ten thousandths column from the top number:
6-2=4
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 3 | , | 4 | 9 | 7 | 6 | |
| - | 1 | , | 5 | 5 | 2 | 2 |
| , | 4 |
Subtract the numbers in the thousandths column from the top number:
7-2=5
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 3 | , | 4 | 9 | 7 | 6 | |
| - | 1 | , | 5 | 5 | 2 | 2 |
| , | 5 | 4 |
Subtract the numbers in the hundredths column from the top number:
9-5=4
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 3 | , | 4 | 9 | 7 | 6 | |
| - | 1 | , | 5 | 5 | 2 | 2 |
| , | 4 | 5 | 4 |
Because the upper digit (4) in the tenths column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (14).
