May 13	revised	Is it wrong to tell children that 1/0 = NaN is incorrect, and should be ∞? deleted 56 characters in body
May 13	comment	Is it wrong to tell children that 1/0 = NaN is incorrect, and should be ∞? Oh, you mean the shortcut I took? well that's what was confusing everyone else, so I put it. I know it's mathematically wrong. removed it. It's a language shortcut that tends to become a rule overtime :p

May 13	comment	Is it wrong to tell children that 1/0 = NaN is incorrect, and should be ∞? @Asaf Karagila, yes I made a mistake there, it's the right limit of 1/0 which is +infinity, where the left limit is -infinity :) This is kinda of old, haven't done that in years
May 13	comment	Is it wrong to tell children that 1/0 = NaN is incorrect, and should be ∞? It's actually $$\displaystyle\lim_{x\to 0^+}(1/x)=+\infty$$ since dividing a positive number by another positive number returns also a positive number :)
