1=0 'proof' rely on divide by 0. Is there any that don't

Syth · 2003-04-23 15:02:28

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…
