Line 4 is wrong, February 15, 2013 too cool, June 29, 2012 Funny, but faulty., March 9, 2010Posted By: M. Hammes
I enjoy the joke, however this is faulty reasoning. If x=y, then x-y=0. You cannot divide by zero, e.g. n/0 is undefined. Therefore there is no proof that 1+1=1!Even discounting that, the steps where a term includes something multiplied by (x-y) makes the term zero, anyway, so all we are proving is zero=zero.Funny shirt, though!

The "proof" is wrong. At the beginning, you assume x=y. Later on, when you have (x+y)(x-y)=y(x-y), you divide (x-y) assuming that x does NOT equal y; therefore, contradicting your initial assumption. This t-shirt just shows how mathematically disabled you are.
