Soluzione - Long subtraction
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 2 | 4 | 3 | , | 5 | 1 | 6 | |
| - | 1 | 4 | 5 | , | 6 | 4 | 9 |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (6) in the thousandths column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (16).

Subtract the numbers in the thousandths column from the top number:
16-9=7

Because the upper digit (0) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (10).
