So I recently join an engineering course, in my pure math classes we are currently studying basic algebra, simultaneous equations or quadratics. I quickly found all this very abstract and presented as facts. Now, I dont know how to phrase this, rather than looking for a book that just states what laws of indices are, and so on. Im looking for a book that would explain these more as maybe a full concepts and its cleverness if you will. I have heard that some people like a book called 'A most elegant equation' but I dont even know how relevant it would be. What would you recommend?
