Greetings:

Listen, Iv'e been trying to learn about binary numbers. The problem is, just when I THINK I have the concept down.... I don't. I know the whoal thing about hex numbers, but I just can't GET binary numbers. Please, someone write a tutorial, as simply as possible, about binary numbers.

P.S. = I know the thing about 0x in hex numbers being like a substitute for subscripts, but, what's with that? Why just 0x, what number is it representing?
