Answers to 2-hour clock questions

The standard name of an even integer is 0; the name of an odd integer is 1.
Example: 192807 = 1 (mod 2).

This may seem so simple as to be pointless, but it is actually very important in computer science: all numbers are 0 or 1. Computer science also uses a system of writing regular integers with 0s and 1s called base 2 or binary. This is not the same a clock arithmetic, but it is related.
