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 |
3 | 0 | 1 | , | 5 | 9 | ||
- | 4 | 4 | , | 2 | 2 | 3 | |
, |
Put zeros in the blank number places:
Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
3 | 0 | 1 | , | 5 | 9 | 0 | |
- | 4 | 4 | , | 2 | 2 | 3 | |
, |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the thousandths 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 (10).

Subtract the numbers in the thousandths column from the top number:
10-0-3=7

Because the upper digit (1) in the ones column is too small to get a positive difference, borrow 1 from the number to the left (30) which becomes (29) and get (11).
