(1+1=0) not binary
I wouldn't call the first (1+1=0) binary. "Binary" is a way to write symbols for the natural numbers . There, 1+1=2. Writing it binary as doesn't change the result, it's just two different symbols representing the same number. In contrast, is a different thing. You can imagine as a 180 degree rotation. 1+1 would than mean rotating by 360 degrees. The result is the same as if the rotation didn't take place: That's , and therefore 1+1=0, without any tricks like ignoring the overflow bit of an adder circuit. -- JeLuF 21:29 13 Jun 2003 (UTC)
Chinese joke
A Chinese joke: What is "1+1"? Answer: 王 (wang).
Eh? I don't get this. Is it just that the character can be made from the characters "1", "+", and "1" combined? If so, I don't see why it's funny... If this is a well-known joke among Chinese people, this fact needs to be explained in the article, and the joke itself should be explained. Otherwise, it should be removed. -- Oliver P. 22:44, 21 Aug 2003 (UTC)
