Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 2 | , | 7 | 8 | 6 | |
| - | 3 | , | 5 | 2 | 2 | |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
6-2=4
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 2 | , | 7 | 8 | 6 | |
| - | 3 | , | 5 | 2 | 2 | |
| , | 4 |
Subtract the numbers in the hundredths column from the top number:
8-2=6
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 2 | , | 7 | 8 | 6 | |
| - | 3 | , | 5 | 2 | 2 | |
| , | 6 | 4 |
Subtract the numbers in the tenths column from the top number:
7-5=2
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 2 | , | 7 | 8 | 6 | |
| - | 3 | , | 5 | 2 | 2 | |
| , | 2 | 6 | 4 |
Because the upper digit (2) in the ones 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 (12).

Subtract the numbers in the ones column from the top number:
12-3=9
| Place value | tens | ones | . | tenths | hundredths | thousandths |
| 0 | 12 | |||||
| 1 | 2 | , | 7 | 8 | 6 | |

| 9 | , | 2 | 6 | 4 |
Write 0 in the tens place.
