> how someone can overengineer a solution

If his solution doesn't work with arbitrary number-like objects (matrices at the very least), doesn't support voice input, can't send results via email and can't seamlessy resume the calculations after a hardware failure, it's far from overengineered.

Matrices don’t form a field so I would say they are not really “number-like” in the full sense.
