1.715
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 1 | 7 | 3 | 0 | |
| - | 1 | 5 | ||
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ones column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (10).
| Place value | thousands | hundreds | tens | ones |
| 2 | 10 | |||
| 1 | 7 | 3 | 0 | |
| - | 1 | 5 | ||
Subtract the numbers in the ones column from the top number:
10-5=5
| Place value | thousands | hundreds | tens | ones |
| 2 | 10 | |||
| 1 | 7 | 3 | 0 | |
| - | 1 | 5 | ||
| 5 |
Subtract the numbers in the tens column from the top number:
2-1=1
| Place value | thousands | hundreds | tens | ones |
| 2 | 10 | |||
| 1 | 7 | 3 | 0 | |
| - | 1 | 5 | ||
| 1 | 5 |
Write 7 in the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 2 | 10 | |||
| 1 | 7 | 3 | 0 | |
| - | 1 | 5 | ||
| 7 | 1 | 5 |
Write 1 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 2 | 10 | |||
| 1 | 7 | 3 | 0 | |
| - | 1 | 5 | ||
| 1 | 7 | 1 | 5 |
The solution is: 1,715
