Solution - Long subtraction
14.497
Step-by-step explanation
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).

Subtract the numbers in the hundredths column from the top number:
12-3=9

Because the upper digit (3) in the tenths column is too small to get a positive difference, borrow 1 from the digit (9) in the next number place which becomes (8) and get (13).

Subtract the numbers in the tenths column from the top number:

Subtract the numbers in the ones column from the top number:
8-4=4
