See my comment #145. He's not just dumbing down his poor students a little bit, he's making them truly stupid.

I disagree. It seems to me he's introducing them to a truly interesting concept of math. He hasn't introduced a "proof" that it's possible to divide by zero. It seems more that he has devised a convention for an algorithm to decide what to do in the case where a number is divided by zero.

No, he calls it a "theorem." That means he claims to have a proof.
