You do realize that there are mathematical equations for dividing by zero? And that the square root of minus one being incalculable is more of a current limitation of our bio-logical mathematical circuits than an actual incalculable equation? Why on earth would you assume that Arael would have a problem with that piece of division?
I was answering @MWKillKenny84's question about the inside of Deadpool's head by alluding to the joke that "Black Holes are where God divided by zero." Considering this is Deadpool, I threw in i just to make the expression a little less real.
And I never said Arael would have a problem with it. I also never said it was unsolvable. Under certain conditions, you can get a useful answer out of dividing by 0, like l'Hôpital's rule, or certain applications in matrix or abstract algebra. Those techniques all require specific conditions be met. Baring explicitly declaring those conditions, one must assume they do not exist. In which case, there is no meaningful answer to a constant divided by 0
i isn't "incalculable," so much as it does not exist within the set of all Real Numbers. It is an abstraction created to address limitations of the Real Numbers. A set of rules were developed that treated Imaginary Numbers as a special case, within a larger framework.
