Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths | thousandths |
| 9 | , | 1 | 2 | 4 | |
| - | 0 | , | 3 | ||
| , |
Put zeros in the blank number places:
| Place value | ones | . | tenths | hundredths | thousandths |
| 9 | , | 1 | 2 | 4 | |
| - | 0 | , | 3 | 0 | 0 |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
4-0=4
| Place value | ones | . | tenths | hundredths | thousandths |
| 9 | , | 1 | 2 | 4 | |
| - | 0 | , | 3 | 0 | 0 |
| , | 4 |
Subtract the numbers in the hundredths column from the top number:
2-0=2
| Place value | ones | . | tenths | hundredths | thousandths |
| 9 | , | 1 | 2 | 4 | |
| - | 0 | , | 3 | 0 | 0 |
| , | 2 | 4 |
Because the upper digit (1) 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 (11).
| Place value | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||
| 9 | , | 1 | 2 | 4 | |
| - | 0 | , | 3 | 0 | 0 |
| , | 2 | 4 |
Subtract the numbers in the tenths column from the top number:
11-3=8
| Place value | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||
| 9 | , | 1 | 2 | 4 | |
| - | 0 | , | 3 | 0 | 0 |
| , | 8 | 2 | 4 |
Subtract the numbers in the ones column from the top number:
8-0=8
| Place value | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||
| 9 | , | 1 | 2 | 4 | |
| - | 0 | , | 3 | 0 | 0 |
| 8 | , | 8 | 2 | 4 |
The solution is: 8,824
