That isn't how math is done at a high level. That is mechanical rote computation, which in higher-level courses and in the real world is done by computers. Real math is all about, roughly, creating the formulas that the software will use, which means you have to prove that the formula is both logically correct and does what you want to do. It's a creative act. If you remember nothing else, remember that high-level math is creative.
