FACTORIALS and PERMUTATIONS - DISCRETE MATHEMATICS

Today we introduce factorials, permutations, and permutations without repetition. We also do a few practice problems.

I've taken many STATS, MATH, DISCRETE STRUCTURES courses throughout university and I can say without doubt you are the only person that could explain such a fundamental concept like permutations so flawlessly. You're the best.

Im studying Computer Science at univeristy. My professor said: search "x" book in the library, copy notes, and do assignments... that's all he's really done. You make this topic so much easier to understand than a 4 inch thick book can!

... Did i actually understand it? No wait I did understand it.
*the teacher in our university never explained it this good*

Holy moly, how is it that a teacher that lectures for an hour, makes it so hard to understand anything, but you are able to make me understand it in 15 minutes?! Thank you so much for these videos!!

You make discrete maths seem much more intuitive than it previously did for a calculus oriented person like me. Keep up the good work Trev!

This is actually amazing. Sometimes I feel stupid because I can't understand my university professor and then I find something like this that I can understand perfectly! So frustrating!

[KartiKKaushiKYt]

I just want to take a momment and appreciate you and your videos. These videos have helped me a lot with my discrete math unit at uni. Thank you!

[toomuchtruth]

This is amazing. Learning this stuff feels almost like learning a magic trick. Thanks alot!

Thank you, I would have been lost without these clear and well-communicated simple explanations. My professor just reads out proofs, without actually explaining them in such simple terms.

am i understanding this after paying so much to my collage and not understanding anything why are you so good at teaching sir im subbing to you and thank you for spreading your knowledge.

[thelonearchitect]

You and Khan are really awesome at teaching such things in a truly intuitive way. That's what missing in university.

[davidmuwowojr]

This channel is like an Easter egg waiting to be discovered, thanks a lot. For the first time I enjoyed learning math, this guy deserves a medal.

[turjosarker]

Flawless explanation. I wish all tutors could explain like this.

[jadewang]

This is the best method I have seen. Thank you so much

[ripjaw]

Thank you so much for you videos. They’ve been a massive help in my understanding discrete math while I have to learn online due to COVID-19

I'm taking remedial Algebra 1 and 2 in community college right now and this is fascinating to me.

[mandeepkafle]

Trev you made me think was this so easy.Great explanation.

[aliasgar]

Loved the path finding example. This could be a much faster solution than backtracking(given the same constraints) for programming problems.

[adarshnathaniel]

Wow I love ur videos soo much. Thanks for the magical trick 😁

[THANOS-kqeh]

Brooo u just made me understand everything within 15 mins damnnn
