2.117
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | thousands | hundreds | tens | ones |
| 2 | 5 | 0 | 0 | |
| - | 3 | 8 | 3 | |
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 number to the left (50) which becomes (49) and get (10).
| Place value | thousands | hundreds | tens | ones |
| 4 | 9 | 10 | ||
| 2 | 5 | 0 | 0 | |
| - | 3 | 8 | 3 | |
Subtract the numbers in the ones column from the top number:
10-3=7
| Place value | thousands | hundreds | tens | ones |
| 4 | 9 | 10 | ||
| 2 | 5 | 0 | 0 | |
| - | 3 | 8 | 3 | |
| 7 |
Subtract the numbers in the tens column from the top number:
9-8=1
| Place value | thousands | hundreds | tens | ones |
| 4 | 9 | 10 | ||
| 2 | 5 | 0 | 0 | |
| - | 3 | 8 | 3 | |
| 1 | 7 |
Subtract the numbers in the hundreds column from the top number:
4-3=1
| Place value | thousands | hundreds | tens | ones |
| 4 | 9 | 10 | ||
| 2 | 5 | 0 | 0 | |
| - | 3 | 8 | 3 | |
| 1 | 1 | 7 |
Write 2 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 4 | 9 | 10 | ||
| 2 | 5 | 0 | 0 | |
| - | 3 | 8 | 3 | |
| 2 | 1 | 1 | 7 |
The solution is: 2,117
