How to learn the Maths for Machine Learning quickly

Math is absolutely necessary for the study of Machine Learning or Artificial Intelligence. Any deeper understanding of the concepts and algorithms in ML requires some basic maths knowledge. Linear Algebra, Statistics, Probability and Differential Calculus appear all throughout ML, and you've probably read that you should study these for 2 or 3 months before even getting into the basics of ML. Well, i'm here to tell you that this is not the best approach. Keep reading and I'll list some resources and show you ways how you can get this done a lot quicker than 2 or 3 months.
