To solve this problem, we'll follow these steps:
Let's break this down:
Step-by-step Solution:
1. Subtract the rightmost digit:
- Subtract 6 from 5. Since 5 is less than 6, we need to borrow from the next digits.
2. Borrowing:
- The immediate next digit is '0', so we continue borrowing to the left. We borrow 1 from the third zero (turning it into a 9), which makes the second zero a 9 and the third zero a 9, and we subtract the borrowed 1 from the 7, turning it into 6.
3. Complete the subtraction:
- For the units column (now 15 and 6), subtract to get: .
- For the tens column (now 9 and 2), subtract to get: .
- For the hundreds column (now 9 and 1), subtract to get: .
- For the thousands column (6 and 4), subtract to get: .
- For the ten-thousands column (no borrowing needed, 6 and 2), subtract to get: .
The final result after all column-based subtractions, including borrowing corrections, is: .
Therefore, the solution to the problem is .
