Proof of 0=1 ------------ Note that I did not think of this. The fact that it is clever and such should have suggested this right away. I think it is the best of the 0=1 proofs I have seen. Recall how multiplication works: when you multiply 3*5 that is like adding three to itself five times. To put it another way, when you add a number n to itself m times, the result is simply n*m. This is true for any n,m. So let's add x to itself x times: x + x + ... + x = x*x = x^2 \____________/ x elements Now take the derivative of this equation: 1 + 1 + ... + 1 = 2x \____________/ x elements or x = 2x hence 1=2 Subtract one from each side and you get 0=1. Note that once 0=1, you get that any number equals any other number.
