>>12917517Assuming you know how to add/divide/subtract and multiply.A little bit of basic set theory won’t hurt.
Then you get Gelfand’s Algebra(this really should be your first book). Trigonometry and Functions & Graphs.
Lang’s Basic Mathematics.
Start working through those and anything you don’t understand refer to youtube, purplemath, patrick jmt.
After that you should be able to tackle Calcalus, Linear Algebra and whatever the fuck you intend to study in maths.
