I would recommend some MOOC's for a good, pressure-free re-introduction. Udacity has an algebra class. I assume it's really good. The Norvig course I took there was excellent. Also check out Coursera. https://www.udacity.com/courses https://www.udacity.com/courses https://www.coursera.org/courses https://www.coursera.org/courses If your interest is math for programming, you want an introductory course or book on 'discrete mathematics', which should be enough math for you to take an algorithms and data structures class. That will position you to do some real programming. Beware of trying to learn everything. For adults that is probably impossible due to time constraints. Standard subjects like trigonometry and calculus will have less utility for programming than discrete math. Focus on algebra and discrete math. Then, if you want more, probability and statistics. That will give you the biggest bang for the buck.
