Solution - Long subtraction
83.11
Step-by-step explanation
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 tenths column from the top number:
10-9=1

Subtract the numbers in the ones column from the top number:
3-0=3
| Place value | hundreds | tens | ones | . | tenths | hundredths |

| 1 | 0 | 4 | . | 0 | 6 | |
| - | 2 | 0 | . | 9 | 5 | |
| 3 | . | 1 | 1 |
Because the upper digit (0) in the tens 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 (10).

| 3 | . | 1 | 1 |
Subtract the numbers in the tens column from the top number:
10-2=8
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 0 | 10 | |||||
| 3 | 10 | |||||
| 1 | 0 | 4 | . | 0 | 6 | |
| - | 2 | 0 | . | 9 | 5 | |
| 8 | 3 | . | 1 | 1 |
Write 0 in the hundreds place.

| 0 | 10 | |||||
| 3 | 10 | |||||
| 1 | 0 | 4 | . | 0 | 6 | |
| - | 2 | 0 | . | 9 | 5 | |
| 0 | 8 | 3 | . | 1 | 1 |
The solution is: 83.11
