Out of curiousity, Why did it take roughly 5-6 years to teach Algebra in the K-12 system, then 1.5-2 for calculus 6th grade prealgebra 7th grade more prealgebra 8th grade even more prealgebra 9th grade algebra I 10th grade algebra II 11th grade basically precalculus stuff, which isn't very far removed for algebra II I swear 6th- 8th grade was a repeat of the same material. some geometry, probability and trigonometry is thrown into the mix. This sums up my experience of K-12 math education. then calculus is taught in 3 semesters (1.5 years). I mean it seems like I literally spent 6 years to learn algebra and 1.5 to learn calculus, yet calculus is far more encompassing and complex. I don't know how it took so long to teach us how to do logarithms, exponentials, and algebraic equations..this is a quandary.
