complex numbers were made so you can have a solution to the equation

x^2 + 1 = 0

it's not "made up"

Remember OP, math is about solving problems- not making shit up because it's complicated. Complex numbers are the *solution* to a problem. Likewise, Quaternions are the *solution* to a problem, as are octonions and any 2^n dimensional coordinate system.

set theory on the other hand was *not* invented to solve ANY problems and has only created more problems than it solves so you should be skeptical of that. If you are going to be call bullshit on a mathematical "theory" do it to set theory. it is utterly redundant and doesn't solve any long outstanding problems that previous mathematical methods could not.

But not complex numbers. Complex numbers are good guys. have you ever seen plots of complex functions? they're cool as shit and electrical engineers use them.
