So, I wanted to learn some math, specifically discrete mathematics, calculus and linear algebra but I don't know which resources are good or the best, if it helps, I can use both videos and text but I prefer text just slightly, and I already know some stuff since I am in 9th grade, I would also value if you all have any suggestion in another math area that I should learn or that could be useful (also thanks to a comment that pointed it out, I do NOT plan to learn them all at once, and I wanna learn them since I heard that they are pretty important in CS and programming)
