But once you start kind of getting the concept of vectors and matrices down, I would not let the math intimidate you and keep you from starting. You can learn quite a bit of it as you go. Seriously, if you can make it through my 3 hours of video and not feel completely lost, I think you're ready to start. I just hate to see you think that you have to get a graduate degree in mathematics before you can put a sprite on the screen and make Pong.
