As someone too poor to afford a university education, thank-you for these videos. They are an immense help to someone trying to go through the textbook alone.

Professor Brehm, I wanted you to know that I got a 99 on my Discrete Math exam!!! I was able to bring my overall to an A, and it's mostly because of your help. Thank you so so much! Your videos are absolutely priceless.

[elipeveto]

I will say this. You are my actual discrete professor now! I’m nearly at the midterm and only your videos actually teach me the material. Great work your a life savor teach!

[wolfxlover]

Thank you *so* much for uploading this videos. I'm taking a Computer Science course that is a Discrete Maths course in disguise. They make it a block period, so the professor lectures for 2 hours. I do not have this attention span no matter how much I want it, and it was really stressing me out. These videos are infinitely helpful.

[LettuceBall]

I wish I had known about these videos in the beginning of the semester. Thank you so much!

[IhavelicensetoDrive]

Thank you for these videos!! Gonna get me through discrete math.

[mzaki]

This channel is a gold mine and the youtube algorithm is not doing a very good job.

[Alaa-wuck]

Thank you very much for how well you explain things! You explain it better than my prof!

[techjesus]

commenting this on every video so u get more reach because these are really helpful and it means way too much to me.

[potatoitis]

Thank you so much for making me feel more confident in discrete math!!! You’re the best.

The best Discrete Mathematics Lectures ...Wowww Thank you so much.

[alexjohnston]

Great series of videos! Just for the sake of completeness: Real Numbers (~3:30 in this video) should also include Irrational Numbers. What is the common notation used for Irrational Numbers? I (bold uppercase i)?

[clydeherbert]

Im going to get this book. Im taking linear algebra right now and this will help me

[mortalwomprat]

This is awesome. Reviewing for my FE. Thank you!!

A better definition of "set" is probably : collection of unordered, unique AND well defined objects.
Any collection with repeated elements can be reduced to a set without any repeat (unique elements only).

[syamalchattopadhyay]

Best video lectures. Excellent clarity.

[Shifticek]

a note for 5:25 - that is true if x is Real number. if x was integer then it would be set of 2 values ( 0 and 1)

[SuperMan-ujdh]

In our discrete math class, natural numbers actually include 0. I have no idea why!

[alisonband]

I wish you could come to UT San Antonio. You are such a good teacher.

[HalloBro]

In positive and negative integers. Do we also consider 0 as part of it?
