Sorry for not answering for quite a while, my computer hasen't been letting me get on gbatemp. I posted this thread/topic or whatever you want to call it because I had just learned an easier simpiler way to calculate in binary. It all started on February 17th when I had the bright idea to tell my math teacher about the binary numeral system, that whole day I spent writing down the numbers/bits of binary from 1 and up, it took me about 2 hours, but at the end of the day, I had finally counted up to the 256th number/bit in binary, 11111111, while I was writing the numbers/bits down I thought of a theory, an odd theory, but a theory, the theory was to assign each binary number/bit to a decimal number, and whatever happened to the decimal number happened to the binary number, the theory looked like this,
2 = 10
3 = 11
6 = 110
so 10 * 11 = 110 or 110 / 11 = 10
because 2 * 3 = 6 and 6 / 3 = 2
anyway that was what the theory looked like, fortunatly, my theory was correct! The next day I told my math teacher that my theory was correct, she was amazed, partially because all of this went in one ear and out the other to her, and secondly because binary is hardly ever thought of anymore even though we use it in every day life. I was excited, so I decided to share the information, then I tried to teach some of my friends about binary, one of them caught on right after they knew how to count, as for the others, I don't think they cared much, except my science teacher, my P.E. teacher, my math teacher and a few others. So as I posted earlier, I would post some pictures of my work (scans really), and well, here they are, at this folder,

did you know you could count up to 1,024 with the fingers of your hand? if you assign 1 bit to each of your fingers.
and malformed people with 11 fingers, the lucky bastards, can count up to 2,048
oh and it gets better if you use your toes... count up to 1,048,576 !
Well, actually having 11 fingers is a dominate trait, however not many people have 11 fingers because not many people have biological parents with 11 fingers.

So this multiplication is correct, right?
EDIT: So i calculated it on paper again and got the right answer, 110110101.
in my early calculation it only had 8 digits, weird...
Yes, that mutiplication is correct. I've seen how to calculate directly, but it looked a little too difficult, so I found a solution/alternative.
