83,11
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 0 | 4 | , | 0 | 6 | |
| - | 2 | 0 | , | 9 | 5 | |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
6-5=1
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 0 | 4 | , | 0 | 6 | |
| - | 2 | 0 | , | 9 | 5 | |
| , | 1 |
Because the upper digit (0) in the tenths column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (10).

Subtract the numbers in the tens column from the top number:
10-2=8
