Yes, but it is a tiny fraction of "general education in math", and there is no causal connection between performance in those two. You'll be able to improve yo

Yes, but it is a tiny fraction of "general education in math", and there is no causal connection between performance in those two. You'll be able to improve your mental arithmetic performance by orders of magnitude from pure memorization + practice alone, but this is not how people typically learn math in general, and rote memorization will not make you a good mathematician in the long run (it's probably not even good enough to get you past university-level exams).
