RIP in Peace, OP
How will he recover?

i just realized i forgot how to second grade arithemetic

subtract 9.99 from 19.00 show all of your work i literally forgot how to do it

Hey, /sci/. I want to learn math and science. I have a very(VERY) fragmented knowledge on these two subjects. Some matrix stuff, some vector stuff, some highschool level algebra, some euclidean geometry, some newtonian stuff, some optics and so on. I can't emphasize enough on how fragmented this is. Which means that I can't really do much with what I have. I want to get on a level where I understand math, science and problem solving enough to prove things by myself, make my own systems, write my own renderer, etc. Basically be able to reinvent the wheels so I can fully understand what I'm doing.
So, my question is-- is there any good book, or a list of good books with a "path" that will take me from middle school level to advanced math and science?
I've tried KhanAcademy but I find the explanations rather long winded and time consuming, I'd rather understand the concepts fast and start solving practice problems right away(MathIsFun helps but I have no idea what I should be learning or in what order things should be learnt).
Thanks
