I am starting IT studies. As someone always interested in computers I have paths in my head how to get needed information. There is also a luxury of testing anything learn in practice by for ex. contributing to open source or creating a server.
Math was always interesting for me too, but I haven't spend time on learning it much, I have many lacks from middle school and there are topics I know about but can't use them in practice or have no intuition or forgot how to formally write them.
So I started to try to learn, as a self-learner most time I spend on Wikipedia and forums, but those turned out to be death end when it comes to understanding whole topic and not just reminding one thing.
So question to you that are learning math: how do you do so? And I also never learned anything in a typical "school" way, I always need to feel interest or have a goal in something.
Take a look at Engineering Mathematics by KA Stroud. It has a step-by-step approach with worked examples that might be useful to you. Even if you don't like the structure, it'll at least give you a comprehensive list of topics.
