I recently enlisted in the US Air Force so I am not attending school this semester; however, I'm still trying to continue strengthening my mathematical skills as well as adventure into new parts of mathematics. I've recently purchased a few new textbooks on an assortment of math subjects and I have run into a problem. That problem is simple. I do not know a good way to take notes from a textbook. Usually, I just take lecture notes from my professors since they basically serve you the important points on a platter. So how do I know which points I should write down and which I should not? Is there an easy method to note-taking from math textbooks? Any help, information, or tips are greatly appreciated.
