Problem: Rounding Numbers to the Nearest 10

The task is to round each given number to the nearest 10. The rules for rounding are as follows:

1. If the number is already a multiple of 10, don't change it.
2. If the ones digit is less than 5, round down by changing the ones digit to zero.
3. If the ones digit is 5 or more, round up by adding one to the tens digit and changing the ones digit to zero.

Examples Provided:

- 27 → Rounded up to 30 because the ones digit is 7.
- 53 → Rounded down to 50 because the ones digit is 3.
- 30 → Unchanged because it is already a multiple of 10.
- 55 → Rounded up to 60 because the ones digit is 5.
