I was about to drop this class, but you saved my life. I am spending more time on your videos than my actual lecture. You explain it in a super simple way. Thanks for your videos.

I literally can't understand my professor (and I am not the only one in my class who feels this way). I am desperately trying to pass Discrete Math, so thank you for all of your help!

My professor should donate half of her salary to you. How is it that I learn more from these short videos than what we cover in a 3hr and 20 minute lecture lol AND it covers more! insane!

I feel so bad for the discrete math students from over a year ago who had bad professors and couldn’t have access to this series. I can listen/watch these videos at work and I am able to get so far ahead

You are helping me so much in my discrete math class it's unreal.

[MAGANAFRANS]

I was really struggling with this topic but this video has really saved me. Thank you so much Miss Brehm.

[waifusaii]

Your videos are sooo helpful you have no idea. I have been relying on you for the entirety of my course. Thank you!

This was the treasure trove of Explaining Quantifiers

These are the best D.M. classes that I have found on YouTube so far...
Thank you professor ❤️ from 🇧🇩

[NOORK]

i dont know how to thank you, im trying to catch up with my lectures bc i dont understand my prof. Youre saving me so much right now<3

[Perichron]

I'm trying to teach myself math. Thank you for being so helpful, you're videos are great.

[devinnicolebaione]

Thank you so much! My online professor has only provided the textbook and cengage as learning tools and I have been completely lost in the sauce, neither is helpful at all. You have made my life so much easier.

Hi Kimberly for x squared <0 why isn’t the existential quantifier true? For example: (negative 5 squared is less than 0) thanks in advance

[giftedgamer]

When I had class I was like “I'm not going today ill just learn from your videos”😂😂😂

[fleventyfive]

Thank you queen <3 I love your videos.

[daltonjohnpalma]

tbh my mind was totally blown right now and I couldn't understand any of the topic but hopefully i could catch up with this.

[RenaJAllDay]

I have a D in this class right now 😢😢 Thanks for helping me try to bring it up!

@11:15 or so, ExP(x) mentioned as false, however, if using 0 like in the AxP(x) example, wouldn't 0 make ExP(x) True?
