Soluzione - Long subtraction
36,3
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths |
| 5 | 2 | , | 3 | |
| - | 1 | 6 | ||
| , |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths |
| 5 | 2 | , | 3 | |
| - | 1 | 6 | , | 0 |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the tenths column from the top number:
3-0=3
| Place value | tens | ones | . | tenths |
| 5 | 2 | , | 3 | |
| - | 1 | 6 | , | 0 |
| , | 3 |
Because the upper digit (2) in the ones column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (12).
| Place value | tens | ones | . | tenths |
| 4 | 12 | |||
| 5 | 2 | , | 3 | |
| - | 1 | 6 | , | 0 |
| , | 3 |
Subtract the numbers in the ones column from the top number:
12-6=6
| Place value | tens | ones | . | tenths |
| 4 | 12 | |||
| 5 | 2 | , | 3 | |
| - | 1 | 6 | , | 0 |
| 6 | , | 3 |
Subtract the numbers in the tens column from the top number:
4-1=3
| Place value | tens | ones | . | tenths |
| 4 | 12 | |||
| 5 | 2 | , | 3 | |
| - | 1 | 6 | , | 0 |
| 3 | 6 | , | 3 |
The solution is: 36,3
