Math is huge so how you approach this will depend a lot on your starting point and your goal. Which branch of math are you interested in? Do you need it for something specific to your career or is it just a hobby? What's you current level - are you comfortable with high-school level algebra, trigonometry, calculus? In any case, I second the recommendation for Khan Academy as a good starting point - not only for the range of content and Sal's silky voice, but also for their approach to learning: you get to practice topics until you "master" them instead of just watching/reading, maybe taking a test and then moving on to the next topic.
