  > The entire book is available for free as an interactive online ebook. This should work well on all screen sizes, including smart phones, and work well with screen readers for visually impaired students. Hints and solutions to examples and exercises are hidden but easily revealed by clicking on their links. Some exercises also allow you to enter and check your work, so you can try multiple times without spoiling the answer.

  I love Cliff Stoll's introduction to this topic https://www.youtube.com/watch?v=W18FDEA1jRQ

  I am yet to find a better introduction than Busby and Kolman's "Introductory Discrete Structures with Applications".

  Beautifully written, concise, very accessible with the precise right amount of formalism.

  Think this would be a great course for high school or even middle school. No plug and chug that makes it a grind, plus a great intro to proofs and deeper mathematical thinking.

  Having just done a discrete math course the best resource has been Kimberley brehms videos on YouTube which follows very closely to a textbook though I can't recall the author at the moment

  This is already brilliant! I feel like giving myself a discrete math refresher.

  Another CC book on discrete Math it's Gentle Introduction to the Art of Mathematics.
