Discrete Mathematics
I believe that it would be helpful to have Discrete Mathematics in your arsenal. It will be great for college students that have a hard time with all the logic that goes into it. Thank you for taking the time to read my post.

As part of our Support Community improvement project, we’re preserving inactive posts that have historical or community value and closing them to new comments. This is one of them!
If this post covers a topic that you’re interested in discussing with the community or requests a feature you’d like to see on Khan Academy, you can try to find an active post about it and add your thoughts (or feel free or create a new post if it doesn’t yet exist in the forum).
I'm inclined to agree. In addition to Khan Academy, I spend some time taking courses from thegreatcourses.com, including one on discrete math by Arthur Benjamin. But courses there aren't free, and they aren't interactive, and you don't score any Khan Academy energy points for taking them.
There are new courses under development all the time at the academy, but resources are limited, and requests for new subjects are numerous.
I second the suggestion / request for Discrete Mathematics! Especially since Khan Academy is trying to encourage and grow people in programming and logic, (and with Discrete Mathematics being one of the major pillars / foundations of Computer Science), it would make an excellent addition and help to further grow students interested in Computer Science.
your wellcome
I agree so much about this. I will be taking a Duel Enrollment course for this in senior year (high school). I go on KA a lot to practice the math I am learning. I could keep up in the class and maybe even try to get ahead of the other students. Also it could help the KA users who intend to go into majoring in Computer Science
Sal, we need you!
I posted about this on another zendesk issue here.
This is what I said:
After having been a hobbyist programmer for several year, going back to school and taking up computer science officially, and after 5 years of study off and on, taking a course Discrete Mathematics ( including Boolean Algebra ) did three things for me.
Boolean Algebra is fundamentally important to computer science. A curriculum or body of learning resources in computer science ( as a science ) or in programming ( as a professional skill ) without Boolean Algebra is incomplete. :)
While Boolean Algebra is a formal system leading into Discrete Math, the entry point, the topic is so much richer: combinatorics, graph theory, generating functions.
I would love to see all of that!
School throws folks into the mix and asks them to make software by a deadline because that is what the industry wants, but without this kind of foundation, they are throwing them to the wolves.
I have an AA in Computer Science, if such a title means anything at all. :( The course I took was in the Information Technology curriculum, which is geared toward IT management. The choice of that course being required for IT, but not for an kind of CS makes zero sense.
I strongly second this request. As an undergraduate of Computer Science, I can say this is the topic that I find very interesting and hard to learn at the same time. I would highly appreciate if there was the Khan Academy course explaining this in the same intuitive manner as the other ones do.
Once I do all the maths on Khan academy I might look at Discrete, and pure and higher maths ad diploma and master degree maths, I don`t care about win or loose its about doing your best.
MIT open courseware have a brilliant course taught by Prof. Tom Leighton which I found brilliant and not extremely difficult to follow.
:)
Is there someone from the Khan staff that can comment on whether this feature request is going to be implemented? Adding discrete math would be a great addition to the site!
Discrete maths taught by Sal would be awesome! It has my vote would be willing to donate extra for that.
I agree. I have a Computer Science degree and this was an important class for building foundation skills that I use in my career as a programmer. It was a class that many people had trouble with and a Khan Academy style of learning for this topic could help many.
A new request on this subject has been made here.
Everyone, please go there and help bring it to the top of recent activity.
I'd vote for that
I believe Discrete Mathematics would be a suitable addition to the Khan Academy library.
I concur. Discrete math please!
I need Discrete mathematics
It will be a great class for me
Yo dawgs its been more than 3 years, either make it happen or tell us you aren't gonna do it

Here is why there has been no movement on this (from Qurora)
It does. For example: Describing Graphs.
Discrete Mathematics is a term that is often used for those mathematical subjects which are utterly essential to computer science, but which computer scientists needn’t dive too deeply into.
But Khan Academy doesn’t cover this in its core mathematics, which culminates in the harder (IMO) calculus subjects, it must be admitted. It follows the classical arithmetic->algebra+geometry->trigonometry->calculus path, with digressions primarily for younger learnes (how to graph, basic stuff like that).
Anyway, the reason is that once you have either learned calculus and everything that comes before it, or struggled with calculus a bit but understood what came before it, the basics of discrete mathematics are quite easy. Some of it will be known from probability (again, available on Khan) such as combinations and permutations.
To rephrase: Discrete Mathematics can either refer to a certain subsection of undergraduate mathematics courses (those that aren’t continuous) or a single course for getting everybody up to speed with what they need (that isn’t continuous) for engineers and computer scientists, as Danah said. But in these, graph theory will be covered in only a few weeks, with independent reading/exercises expected from the students. And undergraduates are not the Khan Academy’s target.
Jefferson - Unfortunately, Khan Academy’s trigonometry course is maybe half complete and has remained in this state since 2015. We’re approaching 5 years of virtually no activity in finishing the course.
still watiing.
how to get acess match for junior hight school ?
kindly give me the solution of this question
If A= {-4,-3,-2,-1,0,1,2,3,4,5}. R is defined on A as follows: For all x, y ∈ A, x R y ↔ 3| (x-y)
I would LOVE to see Discrete Math be added to the math curriculum here. Please and thank you <3
I love practicing mastering everything up to Calc 2 but would love love love to practice mastering discrete math (logic problems like sherbaig207 has above, among other things like reading through proofs). Please consider!
I think Discrete Mathematics is incredibly important and it's not an approachable subject for a lot of people. There's stuff from universities, but it's not great. I found the trevtutor videos and practice problems are amazing, and I think with a little work on adding the problems to the website, his courses could be added here as is. Maybe even in a separate section where partner content is added.
The proofs are the hardest part to do online, but you can have the "find the problem in the logic" type exercises, or "Arrange the steps from these options to construct a proof; not all options will be used."
Discrete math would go a long way in getting people ready for higher level CS and university math courses.
I haven't visited this thread in quite a while, but I've been following it.
I think it's time, the jig is up yo! WE NEED THIS AND SO MUCH MORE!
Universities in the US are starting to realize that they are dropping the ball for --CS-- Software Engineering students.
After having gone to a university which somewhat conflated electronics and software engineering, I have a renewed perspective on the subject of what colleges are lacking and how they may be failing us.
Though I do not necessarily disagree that basic electronic knowledge up to and including logic circuitry is useful for dedicated Software Engineering students, it seems that many colleges lack an understanding of what is most important to prospective Software Engineers.
We need to learn logical thinking and problem solving, which is not lost on various electronics or otherwise IT disciplines, but designing, developing, testing and verifying software is wholy different than designing circuits or managing network infrastructures. It is a different way of thinking, a different way of interacting with clients and associates and a different end goal with different strategies for success.
Without a broad, foundational education in all aspects of software disciplines, including Discrete Mathematics and all of its underlying disciplines, without that basic knowledge and literacy, our educations will not prepare us for university or make us competitive with the rest of the world.
So PLEASE find a way to include more dedicated Software Engineering primers including Discrete Mathematics coursework and various topics, ethics and security introductions, etcetera on Khan Academy. Ask for funding, ask for help, bring it up, speak to your associates and contacts. This is vital in a world where software makes or breaks the vast majority of humanity's efforts.

I think it would be something like:
{ { -1, -4 }, { 0, -3 }, { 1, -2 }, { 2, -1 }, { 3, 0 }, { 4, 1 }, { 5, 2 } }
assuming I'm reading the definition correctly as:
xRy ( if and only if ) 3 ( given or such that ) ( x - y )
so since x and y are both selected from A, ∀ ( for all ) x, y ∈ A, then simply chose an x, then chose a y that meets the criteria x - y = 3
