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 | 3 | , | 0 | 3 | |
| - | 2 | 0 | ||||
| , |
Put zeros in the blank number places:
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 0 | 3 | , | 0 | 3 | |
| - | 2 | 0 | , | 0 | 0 | |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
3-0=3
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 0 | 3 | , | 0 | 3 | |
| - | 2 | 0 | , | 0 | 0 | |
| , | 3 |
Subtract the numbers in the tenths column from the top number:
0-0=0
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 0 | 3 | , | 0 | 3 | |
| - | 2 | 0 | , | 0 | 0 | |
| , | 0 | 3 |
Subtract the numbers in the ones column from the top number:
3-0=3
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 0 | 3 | , | 0 | 3 | |
| - | 2 | 0 | , | 0 | 0 | |
| 3 | , | 0 | 3 |
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 | , | 0 | 3 |
Subtract the numbers in the tens column from the top number:
10-2=8
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 0 | 10 | |||||
| 1 | 0 | 3 | , | 0 | 3 | |
| - | 2 | 0 | , | 0 | 0 | |
| 8 | 3 | , | 0 | 3 |
Write 0 in the hundreds place.
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 0 | 10 | |||||
| 1 | 0 | 3 | , | 0 | 3 | |
| - | 2 | 0 | , | 0 | 0 | |
| 0 | 8 | 3 | , | 0 | 3 |
The solution is: 83,03
