  Funny t-shirt,
Posted By:

As soon as I took it to work, everyone tried to figure out the mistake. To me, it's obvious, I won't spoil it for you. But this is a classic math falacy, put on a shirt. I think it's humorous. I'm glad I have it, and would recommend it.

  Line 4 is wrong,
Posted By:

The reason it comes out (1+1) = 1 instead of (1+1) = 2 is because of line 4. On the right side, it should say 2Y(...). If you propagate that correction through, it will end up with (1+1)=2 at the end, as you would expect.

  Funny, but faulty.,
Posted By:

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!

  Not correct.,
Posted By:

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.
