Answer 2

To study elementary (school) mathematics, try to start with the book by D.K. Faddeeva and I.S. Sominsky "Algebra for Self-Education" , it has 530 pages, it is very detailed and completely covers the entire traditional course of the Soviet normal school in mathematics. Here is a link to it (it will last a month).
When you begin to move on to higher mathematics, you need to master, solving all the tasks, for example, the books of I.A. Kaplan "Practical studies in higher mathematics" , in 5 parts ( they are here, in general I recommend this site) - also very detailed and with a detailed analysis, designed for the minimum school level. Then it is worth moving on to books by Zel'dovich like "Higher Mathematics for Beginners", etc. I-welcome to any engineering faculty.
You have to read a lot and visit forums, such as dxdy.ru and others.
