Check out this previous post: http://news.ycombinator.com/item?id=1449799 http://news.ycombinator.com/item?id=1449799 And also, I'd highly recommend art of problem solving. http://www.artofproblemsolving.com/ http://www.artofproblemsolving.com/ Honestly, the best way to discover math is the Hacker's way i.e. find problems to work on and then start working on them even in you don't know how initially. The very digging in process will lead to further discovery and further learning. Now, be sure to check out art of problem solving forums, people ask questions there and there are very good detailed explanations available. Be also sure to check out Street Fighter math (http://ocw.mit.edu/courses/mathematics/18-098-street-fighting-mathematics-january-iap-2008/ http://ocw.mit.edu/courses/mathematics/18-098-street-fightin...) and fermi questions (e.g: http://mathforum.org/workshops/sum96/interdisc/classicfermi.html http://mathforum.org/workshops/sum96/interdisc/classicfermi....) And remember to print out these questions and carry them with you along with tons of scrap paper. Sometimes, it helps just to read a problem and let it sink in over days...
