^Same here, I have taken countless tests using imaginary numbers, but it never went beyond a really pointless exercise in my mind. Now I get it.

It's a shame I paid for all that college and knowing this would have greatly expanded my understanding of a lot of what I learned in my math classes.

EDIT: I guess I learned it in high school though, and the math teacher probably didn't know this either.

Point being, everyone should come across this at some point. It would be beneficial to many math students.
