I hope I didn't make a mistake, that would be embarrassing :\ if you still don't understand it (but of course you do now) then I can recommend 3blue1brown: https://www.youtube.com/@3blue1brown (you should check them out even if you did understand it) Music: Chopin - Chromatic Etude (Op. 10 No. 2) (played by Dimitry Shishkin) I accidentally loved this project, im so sorry, it was a test to see if you can love/favourite unshared projects - it turns out you can. If you're wondering why some of the maths is in a different font, it's because at first I was motivated and made them with LaTeX and imported into Scratch but then it started getting tedious so i just used Scratch's default serif font.
