In maths, an expression only ever equals a single number. You can't say i^i = e^(-pi/2) and then also say that i^i = e^(3 pi / 2), because if i^i equals two things, then those two things are also equal to each other, and then we get that e^(-pi/2) = e^(3 pi / 2), which is wrong.

Riemann surfaces are the only way to fix this. And they're not even that hard to understand, but I'm not sure if you do.

Stop making people confused.
