10,970
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 |
| 1 | 1 | 0 | 5 | 0 | |
| 1 | 0 | ||||
| - | 7 | 0 | |||
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
0-0-0=0
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 1 | 1 | 0 | 5 | 0 | |
| 1 | 0 | ||||
| - | 7 | 0 | |||
| 0 |
Because the upper digit (5) in the tens column is too small to get a positive difference, borrow 1 from the number to the left (10) which becomes (09) and get (15).
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 15 | |||
| 1 | 1 | 0 | 5 | 0 | |
| 1 | 0 | ||||
| - | 7 | 0 | |||
| 0 |
Subtract the numbers in the tens column from the top number:
15-1-7=7
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 15 | |||
| 1 | 1 | 0 | 5 | 0 | |
| 1 | 0 | ||||
| - | 7 | 0 | |||
| 7 | 0 |
Write 9 in the hundreds place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 15 | |||
| 1 | 1 | 0 | 5 | 0 | |
| 1 | 0 | ||||
| - | 7 | 0 | |||
| 9 | 7 | 0 |
Write 0 in the thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 15 | |||
| 1 | 1 | 0 | 5 | 0 | |
| 1 | 0 | ||||
| - | 7 | 0 | |||
| 0 | 9 | 7 | 0 |
Write 1 in the ten thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 0 | 9 | 15 | |||
| 1 | 1 | 0 | 5 | 0 | |
| 1 | 0 | ||||
| - | 7 | 0 | |||
| 1 | 0 | 9 | 7 | 0 |
The solution is: 10,970
