Hello, im 18 years old and im very interested in mathematics. I have only knowlegde of school-matematics (school-Analysis, school-stochastics and a little bit school-linear Algebra) but thats not really interesting. Its basically memorising given methods to solve exercises instead of really understanding what is behind this methods. So, basically my question is: How can I learn higher Mathematics and where to beginn? In fact I already started by learning mathematical proofs (book: 100% mathematical proof). Is it "right" to start with learning proofs? I just thought it would be good because Univerity Analysis/Algebra-books (like Widder) are very hard to understand for me with my school-knowledge. What do you suggest?
