Solution - Long subtraction
30,528
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 3 | 2 | 1 | 8 | 0 | |
| - | 1 | 6 | 5 | 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 digit (8) in the next number place which becomes (7) and get (10).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 10 | ||||
| 3 | 2 | 1 | 8 | 0 | |
| - | 1 | 6 | 5 | 2 | |
Subtract the numbers in the ones column from the top number:
10-2=8
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 10 | ||||
| 3 | 2 | 1 | 8 | 0 | |
| - | 1 | 6 | 5 | 2 | |
| 8 |
Subtract the numbers in the tens column from the top number:
7-5=2
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 7 | 10 | ||||
| 3 | 2 | 1 | 8 | 0 | |
| - | 1 | 6 | 5 | 2 | |
| 2 | 8 |
Because the upper digit (1) in the hundreds column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (11).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 1 | 11 | ||||
| 7 | 10 | ||||
| 3 | 2 | 1 | 8 | 0 | |
| - | 1 | 6 | 5 | 2 | |
| 2 | 8 |
Subtract the numbers in the hundreds column from the top number:
11-6=5
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 1 | 11 | ||||
| 7 | 10 | ||||
| 3 | 2 | 1 | 8 | 0 | |
| - | 1 | 6 | 5 | 2 | |
| 5 | 2 | 8 |
Subtract the numbers in the thousands column from the top number:
1-1=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 1 | 11 | ||||
| 7 | 10 | ||||
| 3 | 2 | 1 | 8 | 0 | |
| - | 1 | 6 | 5 | 2 | |
| 0 | 5 | 2 | 8 |
Write 3 in the ten thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 1 | 11 | ||||
| 7 | 10 | ||||
| 3 | 2 | 1 | 8 | 0 | |
| - | 1 | 6 | 5 | 2 | |
| 3 | 0 | 5 | 2 | 8 |
The solution is: 30,528
