Math question - what is an illegal number?

[rodlox]

Well, I'm watching the movie PROOF, and they mentioned an "illegal zero"...so I checked wiki (yeah, I was desperate) & found no answer there.

btw, is it just me, or is that movie a plausible outcome of any future wherein Charlie has kids? ;D

The only "illegal zero" that I know of is the "undefined zero" where you divide a number by zero. You can't divide anything by zero... so technically, trying would make the operation "illegal."

But, I've never seen the movie... so I don't know. :)

I highly recommend this movie.

and thank you for answering.

I think my mom watched this movie and she told me I really needed to see it... maybe when life gets settled down and I get all moved to Georgia then we'll get netflix to supplement our basic cable and I'll add that to our list. :)
