Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones | . | tenths |
| 1 | 0 | 0 | 0 | |||
| - | 2 | 6 | 3 | , | 5 | |
| , |
Put zeros in the blank number places:
| Place value | thousands | hundreds | tens | ones | . | tenths |
| 1 | 0 | 0 | 0 | , | 0 | |
| - | 2 | 6 | 3 | , | 5 | |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the tenths column is too small to get a positive difference, borrow 1 from the number to the left (1.000) which becomes (0999) and get (10).
| Place value | thousands | hundreds | tens | ones | . | tenths |
| 0 | 9 | 9 | 10 | |||
| 1 | 0 | 0 | 0 | , | 0 | |
| - | 2 | 6 | 3 | , | 5 | |
| , |
Subtract the numbers in the tenths column from the top number:
10-0-5=5
| Place value | thousands | hundreds | tens | ones | . | tenths |
| 0 | 9 | 9 | 10 | |||
| 1 | 0 | 0 | 0 | , | 0 | |
| - | 2 | 6 | 3 | , | 5 | |
| , | 5 |
Subtract the numbers in the ones column from the top number:
9-3=6
| Place value | thousands | hundreds | tens | ones | . | tenths |
| 0 | 9 | 9 | 10 | |||
| 1 | 0 | 0 | 0 | , | 0 | |
| - | 2 | 6 | 3 | , | 5 | |
| 6 | , | 5 |
Subtract the numbers in the tens column from the top number:
9-6=3
| Place value | thousands | hundreds | tens | ones | . | tenths |
| 0 | 9 | 9 | 10 | |||
| 1 | 0 | 0 | 0 | , | 0 | |
| - | 2 | 6 | 3 | , | 5 | |
| 3 | 6 | , | 5 |
Subtract the numbers in the hundreds column from the top number:
9-2=7
| Place value | thousands | hundreds | tens | ones | . | tenths |
| 0 | 9 | 9 | 10 | |||
| 1 | 0 | 0 | 0 | , | 0 | |
| - | 2 | 6 | 3 | , | 5 | |
| 7 | 3 | 6 | , | 5 |
Write 0 in the thousands place.
| Place value | thousands | hundreds | tens | ones | . | tenths |
| 0 | 9 | 9 | 10 | |||
| 1 | 0 | 0 | 0 | , | 0 | |
| - | 2 | 6 | 3 | , | 5 | |
| 0 | 7 | 3 | 6 | , | 5 |
The solution is: 736,5
