Yeah, back in Spring'81 Control Theory they had us do a 5x5 transform by hand (on the midterm) and it was complex/imaginary..
mindexpanding.. You can't imagine how many of those academic menial/manual kind of projects made me look at computer results with greater humility and skepticism than my colleagues who hadn't.. (One econ professor had us take apart a common data series and explain all the times the basis changed, making the observations a lot less comparable than expectyed  a chem professor took off points on an exam for every digit your result had that could not be measured in his lab: if your calculator had twelve digits and his instrument only two you lost 10% of your grade) DOing them once was instructive.. doing them multiple times would have just been cruel..
