What is your specific goal? What are you trying to achieve with math? I would start there first. If your goal is to get a math major level of understanding of math, then I would look at what the standard curriculum is in universities.
Linear Algebra is the language of almost all machine learning, simple geometry and trigonometry are useful in graphics and other aspects of design.
Math, as I said elsewhere, is huge, and there is no single thing that will, by itself, help you to be a good programmer.
If you really have absolutely no math at all then you need to start with some basics, and Khan Academy is a good resource to explore first.
Discrete math is the branch that is most likely to make you a better programmer. Not Kahn academy, etc.
