why cant "undefined" as in x/0 be made into another class of numbers like negative root's complex number

Because undefined isn't a number it is an error message.

you can't devide something into nothing. you can devide it into infinitely many things that "approach" 0.

It's not that we could extend it, it's that when you accept it to be true you get contradictions.

i see no problem with dividing something into nothing. it requires more tolerance than the concept of multiplying something into nothing

but negative root also used to be considered an error?

It can and it was. There is the projectively extended real line and there are wheels. I swear to god, you assholes so fucking lazy you can't even read a fucking wikipedia article. Oh no, wikipedia! You don't even know what's written there, fuck you.

sounds like this needs more investigation

I know x/0=infty in the extended reals, but how is that another class of numbers? The value of x is lost.

let a/0 = c
(a/0 = c) / a
(1/0 = c/a) * 0
1 = 0

is there no way to conjugate infinity?

>(1/0 = c/a) * 0
come on, be serious anon. If you expect multiplying and diving by 0 to make sense, you cannot say c*0=0.

c*0=a. You defined it. (c*0)/a=a/a=1.
1=1. There is no contradiction.
