    We've all seen the proof that show 1=2 or whatever. Somewhere along, you wind up dividing by zero. Is there any 'proofs' out there that 'prove' 1=2 but don't divide by 0, but use some other mistake. I've heards that is you make any mistake yuo can show that 1=0 (adding 1 to each side gives 1=2) so am I just asking for a different aspect of the same thing?


    Man I'm on a roll today, or jus clogging up the board with maths.

    That site is great, looking at the other 'proofs' and trying to find the mistake is like a game, plus you hone your mathematical skill.

    Does anyone know any other site that have 'proofs' like that where you have to look for the mistake?
