Most of the material on our website is simple prose, and math is not necessary to understand it.

The good thing is that the math necessary to understand the most important AI algorithms, especially deep neural networks, is at the high-school level and should be available to most people. For those few subjects that we need, mainly calculus and linear algebra, here are the essentials:
