Hi everybody, I want to ask about this, and Im not exactly sure what 'type' of math this is, so I put it under general math..sorry if its not the correct place for it. Anyways, about a year ago my cousin who went to Georgia Tech, was talking to me about math. I asked him what he thought the most complicated math was, and he says, "Well I think decimal 8 math is the hardest". I asked him what it was and he told me that its a number system or a way of doing math using decimals of 8 instead of 10 like our normal number system. He never took the class, he just said its harder than calculus. So, what is this math? And what is it used for?
