> The worst part is that they are both, in a critical sense, wrong. I thought the worst part is that in context of "normal" mathematics taught in schools one is obviously wrong, and also unable to do research and admit own mistakes, and that one is actually teaching children. > This approach of teaching math as a bunch of universal facts that are either true or false is actively harmful Kids are taught not philosophy or logic but certain mathematical paradigm (that you call "normal") in which division by zero is an error. If you have a formula you decompose it to smaller formulas, if in a smaller formula you have a division by zero you simplify it to zero then you screwed up the entire thing. There's no true or false value for 1/0, the right move is not to play and not solve any equation in which division by zero appears.
