@FIamethrower, imaginary is actually a misnomer. Complex numbers are very much a real thing that have actual impact on everyday society. AC current is perfectly explainable mathematically if one uses complex numbers. Many real world differential equations only have solutions if one considers complex roots of the characteristic polynomial. Ok math lecture over.
These are the kind of jokes my college algebra teacher used to make. But at least he played classic rock on Pandora a lot.
