Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 6 | 0 | 0 | 0 | 0 | |
| - | 5 | 2 | 8 | 1 | 6 |
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 (6.000) which becomes (5.999) and get (10).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 9 | 9 | 9 | 10 | |
| 6 | 0 | 0 | 0 | 0 | |
| - | 5 | 2 | 8 | 1 | 6 |
Subtract the numbers in the ones column from the top number:
10-6=4
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 9 | 9 | 9 | 10 | |
| 6 | 0 | 0 | 0 | 0 | |
| - | 5 | 2 | 8 | 1 | 6 |
| 4 |
Subtract the numbers in the tens column from the top number:
9-1=8
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 9 | 9 | 9 | 10 | |
| 6 | 0 | 0 | 0 | 0 | |
| - | 5 | 2 | 8 | 1 | 6 |
| 8 | 4 |
Subtract the numbers in the hundreds column from the top number:
9-8=1
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 9 | 9 | 9 | 10 | |
| 6 | 0 | 0 | 0 | 0 | |
| - | 5 | 2 | 8 | 1 | 6 |
| 1 | 8 | 4 |
Subtract the numbers in the thousands column from the top number:
9-2=7
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 9 | 9 | 9 | 10 | |
| 6 | 0 | 0 | 0 | 0 | |
| - | 5 | 2 | 8 | 1 | 6 |
| 7 | 1 | 8 | 4 |
Subtract the numbers in the ten thousands column from the top number:
5-5=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 5 | 9 | 9 | 9 | 10 | |
| 6 | 0 | 0 | 0 | 0 | |
| - | 5 | 2 | 8 | 1 | 6 |
| 0 | 7 | 1 | 8 | 4 |
The solution is: 7,184
