I need help PR math books or any procedure that would help me retain knowledge of the subject. I am a beginning PReader but I am familiar with all the techniques. With other subjects it is not as difficult to PR the info but with math books there are so many complicated formulas to understand. I want to learn more on how to mind map because I feel that math is best learned(as well as everything else)by seeing the entire picture visually. I have tried to PR my math books before but they are difficult to activate. Some of the subjects are Discrete math, Combinatorical math, Linear Algebra to name a few. I hope you all can help me, I feel that I am so close.
