Discrete Math - 1.7.1 Direct Proof

This is the first of several videos exploring methods of proof. In this video we will focus on direct proof by assuming "p" is true, then showing that "q" must also be true.

Thank you! You helped me pass my abstract algebra class where our teacher just assumed we all knew how to write proofs and threw a ton of material at us. You’ve allowed me to enjoy pure math again!

[danchatka]

You are less confusing than most videos about math proofs. Thank you for sharing your knowledge and teaching abilities.

[rafay]

She's soooo clear of the rest, easily the best discrete teacher I've come across

3:58 “because.. I just.. I can’t even”

don’t be silly guys. Let’s not disappoint her. She’s my guardian angel this semester♥️. Make sure you’re up to speed with the basics. 😂

Your videos are incredibly helpful. I'm taking this class online and all they give us is a textbook. This has been a wonderful supplement. And the "I can't even" comment had me in fricken tears. :lol:

Lmao I was working ahead, and around 3:55, I had just finished writing n^2 = 4k^2 + 1 thinking I was a god. Then, I heard Dr. Brehm say "Pleaaasee do not give me 4k^2 + 1... because.. I just can't even" and I felt personally attacked 😂

[alayna]

Oh goodness! A teacher who explained the material instead of posturing how smart they are?!? You might just be my favorite person.

[moukafaslouka]

I got a lot from your discrete math videos! Thanks for sharing!

[waleedbensumaidea]

Thank you so much..
I really benefited greatly from your explanation of the lesson. ..
I didn't understand the lesson from the doctor at the University.

But I understood through your explanation
