This is insanity. 80 videos on discrete mathematics. you are a legend miss kimberly

[chrissyg]

You're the reason I understood any of this in class. Thank you!!

When you realize the free content is better than the content you pay thousands of dollars for in tuition fees

[imanfuad]

Teachers/Lecturers don't understand how big of an impact these good videos do, you literally save lives for years and years of thousands !!! God bless you

Just to show how much your work has helped me... I am on an accelerated path to my bs of computer science through WGU. Basically have 31 courses and 122 credits to complete. I have finished 6 courses since october 1st but they were all familiar subjects. Discrete math was something i never encountered before. Because of your discrete mathematics courses i managed to finish the full course in under 72 hours from start to final assessment. I cannot express enough how thankful i am to have found this. It is not a challenge to acquire the knowledge, but it is to convey it, and you did not miss once!

This is a gem for software development.

Thank you Professor Kimberly! I got an A in my first year discrete math course thanks to these videos (my instructor wasn't much help) :)

[LoveEachDay]

im trying to get ahead before i start classes next month and i really appreciate your courses. they're very digestible and easy to understand.

Hello Professor Brehm, I just wanted to let you know that your videos are amazing and incredibly helpful. These videos are the only reason I am getting through my Discrete Math 1 & 2 courses at the moment. My professors are not very good at explaining the material and provide very confusing examples. Thanks for the help!

[johnboy]

Thorough, precise, and magnificent! Thank you, professor, for your help! I am currently in Discrete Mathematics, and these videos seriously mean the world not only to me but also to many others!

[strillics]

I really feel guilty learning all of this and not giving you something back, Thank you so much.

[danas]

your videos have been the only ones i can focus on and follow along with THANK YOU SO MUCH

[RonSheely]

Thank you Professor K. You remind of my first calculus professor at Cal Poly 1971. Dr. Quinn from UK. He had several doctorates. He taught calculus to the dock workers in East London at the pub. I met with Dr Quinn every day during office hours.

These free video help me a lot. Me and my daughter use it to understand her Math class. It looks like there is not a good book to explain easier like this. Thank you Kimberly Brehm!!!!

[billh]

Thanks for being so helpful for linear algebra and Discrete Math

[agiliteaV]

Thank you for these videos, It's not my professor's fault that I can't understand them because of their heavy accent and my hearing disability, but having resources like these makes a world of a difference.

[EvanLikesCake]

Thank you for providing these videos! These helped me so much in my discrete math course!

About a year ago, I was introduced to statistical mathematics, and I remember watching some of your videos. In the last couple of months, I've finally understood the fundamentals of algebra. In other words, I'm very conscious of what a variable means, that it is represented as a letter and so on. I've understood the concept of input, output, algorithm and a mathematical function. I can also read and understand tables and graphical functions much better than before.

Previously on, I could solve for x & y, but I didn't really understand the concept of variable. That's why I didn't understand proofs or definitions in mathematics. Now, however, I do quite well. It's wonderful that one key concept can unlock so many doors for you.

Thank you very much Kimberly, Your way of explaining is very helpful and quick to the brain specially for someone who left school for long time.

Seeing the truth table reminds me of logic gates. Thanks for this. 💖
