Penjelasan langkah demi langkah
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 2 | 5 | . | 2 | 4 | 6 | |
| - | 1 | . | 8 | 5 | ||
| . |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 2 | 5 | . | 2 | 4 | 6 | |
| - | 1 | . | 8 | 5 | 0 | |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
6-0=6
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 2 | 5 | . | 2 | 4 | 6 | |
| - | 1 | . | 8 | 5 | 0 | |
| . | 6 |
Because the upper digit (4) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (14).
