Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 8 | 0 | 0 | 0 | 0 | |
| - | 4 | 7 | 1 | 4 | 2 |
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 (8.000) which becomes (7.999) and get (10).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 9 | 9 | 9 | 10 | |
| 8 | 0 | 0 | 0 | 0 | |
| - | 4 | 7 | 1 | 4 | 2 |
Subtract the numbers in the ones column from the top number:
10-2=8
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 9 | 9 | 9 | 10 | |
| 8 | 0 | 0 | 0 | 0 | |
| - | 4 | 7 | 1 | 4 | 2 |
| 8 |
Subtract the numbers in the tens column from the top number:
9-4=5
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 9 | 9 | 9 | 10 | |
| 8 | 0 | 0 | 0 | 0 | |
| - | 4 | 7 | 1 | 4 | 2 |
| 5 | 8 |
Subtract the numbers in the hundreds column from the top number:
9-1=8
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 9 | 9 | 9 | 10 | |
| 8 | 0 | 0 | 0 | 0 | |
| - | 4 | 7 | 1 | 4 | 2 |
| 8 | 5 | 8 |
Subtract the numbers in the thousands column from the top number:
9-7=2
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 9 | 9 | 9 | 10 | |
| 8 | 0 | 0 | 0 | 0 | |
| - | 4 | 7 | 1 | 4 | 2 |
| 2 | 8 | 5 | 8 |
Subtract the numbers in the ten thousands column from the top number:
7-4=3
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 9 | 9 | 9 | 10 | |
| 8 | 0 | 0 | 0 | 0 | |
| - | 4 | 7 | 1 | 4 | 2 |
| 3 | 2 | 8 | 5 | 8 |
The solution is: 32,858
