The binary system of numbers uses which two digits?

There's 10 kinds of people, those who get binary and those that don't.

teebee303, What a two bit joke.

I used to be able to add, subtract, multiply, and divide binary from a computer programming course I took many years ago. Could I do it now? No way! I do recall, tho that it was easy to learn.

Only 2 of these answers have 2 digits in.
