Here’s the place to offer the most inane bits of faux logic you can come up with. For example: Iron City Beer is from Pittsburgh. Steel is made in Pittsburgh. Therefore, they must use beer in their steel. And, so on. 😃 Cartooniverse ---

My favorite: > [@](#): > > It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. And finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any person you may meet from time to time are merely the products of a deranged imagination." -The Restaurant at the End of the Universe ---

You’re right. > How DOES this work? \*\* Sorry, are you asking why it gives 2=1 (as Another Primate explains 2_0=1_0 doesn’t mean 2=1, because you can’t cancel the zeros) or how I went from xx-yy to (x+y)(x-y) to which the answer is as you seemed to guess, that I’ve seen it before, so I know these two are equal.

As far as I can tell, the lines (x+y)(x-y)=(x-y)y into x+y=y are incorrect…if you were to divide both sides by (x-y) would you not get----- (x+y) = y (x-y) Or am I really doing that badly in my PreCal class? ~Ferry ---

But… (X+Y)(X-Y)=(X-Y)Y Divide both sides by (X-Y) and you get (X+Y)=Y The point of why this doesn’t work? I think it’s that you cannot divide by zero, and so if it is true that X=Y, dividing by (X-Y) produces crazy results.
