made this website for math learning. it's essentially an elo-based math practice website with ranking systems. the main features include a real computer-algebra system, which means that equivalent answers are all marked correct (i.e., 1/2, 0.5, x^2 - 1 is the same as -1 + x^2, factored/expanded forms are all valid answers). even though it still needs work, there's also physics simulations, mainly tailored towards the AP Physics 1 curriculum, to help students visualize physics problems. another beta feature is the teaching section, where teachers can create classrooms and assign problems to students. other features are pretty standard across other learning platforms, including daily puzzles, stats, review for incorrect problems, etc. any feedback would be great!

tldr; math practice site with elo-based ranking, physics problem simulations, teaching interface. feedback greatly appreciated!!
