Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 3 | 8 | 9 | 1 | 1 | 6 | |
| - | 3 | 6 | 5 | 2 | 5 | 6 |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the ones column from the top number:
6-6=0
| Place value | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 3 | 8 | 9 | 1 | 1 | 6 | |
| - | 3 | 6 | 5 | 2 | 5 | 6 |
| 0 |
Because the upper digit (1) in the tens column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (11).

| 3 | 8 | 9 | 1 | 1 | 6 | |
| - | 3 | 6 | 5 | 2 | 5 | 6 |
| 6 | 0 |
Because the upper digit (0) in the hundreds column is too small to get a positive difference, borrow 1 from the digit (9) in the next number place which becomes (8) and get (10).
