Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 9 | 2 | , | 9 | 5 | 3 | 2 | |
| - | 3 | ||||||
| , |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 9 | 2 | , | 9 | 5 | 3 | 2 | |
| - | 3 | , | 0 | 0 | 0 | 0 | |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ten thousandths column from the top number:
2-0=2
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 9 | 2 | , | 9 | 5 | 3 | 2 | |
| - | 3 | , | 0 | 0 | 0 | 0 | |
| , | 2 |
Subtract the numbers in the thousandths column from the top number:
3-0=3
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 9 | 2 | , | 9 | 5 | 3 | 2 | |
| - | 3 | , | 0 | 0 | 0 | 0 | |
| , | 3 | 2 |
Subtract the numbers in the hundredths column from the top number:
5-0=5
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 9 | 2 | , | 9 | 5 | 3 | 2 | |
| - | 3 | , | 0 | 0 | 0 | 0 | |
| , | 5 | 3 | 2 |
Subtract the numbers in the tenths column from the top number:
9-0=9
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 9 | 2 | , | 9 | 5 | 3 | 2 | |
| - | 3 | , | 0 | 0 | 0 | 0 | |
| , | 9 | 5 | 3 | 2 |
Because the upper digit (2) in the ones 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 (12).
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 8 | 12 | ||||||
| 9 | 2 | , | 9 | 5 | 3 | 2 | |
| - | 3 | , | 0 | 0 | 0 | 0 | |
| , | 9 | 5 | 3 | 2 |
Subtract the numbers in the ones column from the top number:
12-3=9
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 8 | 12 | ||||||
| 9 | 2 | , | 9 | 5 | 3 | 2 | |
| - | 3 | , | 0 | 0 | 0 | 0 | |
| 9 | , | 9 | 5 | 3 | 2 |
Write 8 in the tens place.
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 8 | 12 | ||||||
| 9 | 2 | , | 9 | 5 | 3 | 2 | |
| - | 3 | , | 0 | 0 | 0 | 0 | |
| 8 | 9 | , | 9 | 5 | 3 | 2 |
The solution is: 89,9532
