To solve the problem of finding the difference between the largest 5-digit number and the smallest 6-digit number, follow these steps:
1. Identify the largest 5-digit number.
- The largest 5-digit number is 99999.
2. Identify the smallest 6-digit number.
- The smallest 6-digit number is 100000.
3. Calculate the difference between these two numbers.
- Subtract the largest 5-digit number (99999) from the smallest 6-digit number (100000):
[tex]\[
100000 - 99999 = 1
\][/tex]
Therefore, the difference between the largest 5-digit number and the smallest 6-digit number is [tex]\(1\)[/tex].
So, the answer is [tex]\(1\)[/tex].
