Conquering my fear of math

Good evening /sci/.  I posted a thread on /g/ seeking recommendations of good sites to visit for general math practice in varying levels, from Arithmetic to Pre-Calc.  I found math.com, and this seems good, but if you guys know of anything better, please direct me to it.  If you guys also know of any sites that could teach me more advanced stuff like Calculus, that would be very much appreciated. 

I was told to also look into purchasing books.  Are there any that you would recommend?

Math was always one of my weakest subjects, but I've had a recent interest in actually trying to be good at it.  This is mainly due to my new interest in logic.  I will look for your recommendations.  Thank you.
