Discrete Math

Agreed.  I've seen this request quite a few times.  Might be worth searching for and make sure you vote on all of them.

I definitely agree with this! I am taking a course in discrete math (called Discrete Structures at the university I'm attending) and I would definitely love to see this on khan academy. It would have been helpful to prepare for this class better and perhaps different instructors would have different approaches to help computer science majors better understand it. Plus there's nothing like being able to pause and re-watch a video explanation and have online problems with instant feedback. More often than not I am lost during an in class lecture, and the book we have doesn't always explain things well. I think the ability to watch and re-watch would help a lot.

It's odd that Kahn Academy, a company completely reliant on computer science advances, does not offer Discrete Math - courses foundational to computer science education.

Please add a Discrete Math/Structures course. It seems to be the only thing missing from your Mathmatics suite. I would love to prepare prior to taking the course.

I also second this! It's a critical part of a computer science education and the first stepping stone to data structures and algorithms.

For those interested in learning some of the components of discrete math on the KA platform, I would recommend these units:

Probability and Combinatorics:
https://www.khanacademy.org/math/precalculus/x9e81a4f98389efdf:prob-comb

or

https://www.khanacademy.org/math/statistics-probability/counting-permutations-and-combinations

Probability and set theory:

https://www.khanacademy.org/math/statistics-probability/probability-library

A good intro to discrete that I would also recommend is Book of Proof by Richard H. Hammack.

The author provides a free pdf through the open textbook initiative here: https://www.people.vcu.edu/~rhammack/BookOfProof/BookOfProof.pdf

Physical book:

Some good resources have been mentioned. I'll also point out trevtutor. After spending a lot of time trying to find good material, his videos and exercises are by far the best out there. Really great, understandable explanations and good practice problems.
