My only real exposure is helping friends kids with their homework, and it really seemed like they were focused way more on shortcuts to correct answers for simple problems than how and why numbers interact. Which I guess is kinda what you’re saying! Imo those are great techniques for working at a higher level, but in no way a substitute for observing and understanding the processes that lead to those answers. You’ll get plenty of competent accountants that way, but you won’t inspire many mathematicians.
