>>27 is completely correct in saying that no professor (or TA, or department grader) would complain about (a+bi)/c unless it was explicitly stated that your answers should be in the form a+bi (or r*e^(it)). You had a shitty high school teacher; an experience most people will find familiar. That doesn't make your idiotic statement any less true. Do CMU a favor and quit tarnishing its reputation by pretending to know what you're talking about with regards to mathematics.
