Path to learn

I'm totally new to investing, so I've started to gather some resources to start my journey. The intelligent investor is a book that has come up quite a lot in my searches so I've started reading it, but I find that I don't understand more than 50% of most of the statements. How can I overcome the lack of basic concept and technical terms? Can you suggest some book that will help me to understand what I'm reading? I'm not scared of math and equations, perhaps that will clarify more than just a divulgative book.
