Solving functional equations usually does not require heavy prerequisites. Paradoxally, that only makes them more frustrating: they are often much more than plugging random values in the equations. We first briefly describe tvelwe ways of treating functional equations, then we attempt to classify a large number of solved problems according to the method.
