could you make a series on proofs? I'm teaching myself math and i just finished analysis 1 and im finishing linear algebra, i understand proofs in the books but i want to be able to write some good ones on my own.
Dude I love you so much! I was taking Real Analysis, without having taken any proof class [I am an Economics student], and I am struggling so so much in it. And then I found this, and everything is making sense. I hope that by the time I finish your proof series, I will actually be able to solve a question for Real Analysis. In any case, learning a lot!
@BrainGainzOfficial Thank you for this video and series; I'm an older student getting back into math who never had experience in proof writing, so I very much appreciate your style and flow of presenting this subject.
I am trying as I am in Discrete math for computer science and I tried proving before watching the rest and I keep getting it all wrong. >.< Trying to understand but not getting there yet at all. Dx
Really enjoying your videos! I have a question about example number three. I set both x and y to be 2k+1, then after multiplying and factorising i was left with 4k(k+1)+1. 4k would always be even then multiplying an even by an even or an odd (k+1) would always be an even. Finally adding one would give an odd. Is my method also a correct way to go about this? Thanks!
what if he made two versions of the videos: 1) one in the way he wants, and 2) one in a way that presents the proof with no commentary? Perhaps it's because I'm new to Mathematical proof writing, but I actually appreciated his effort to make this subject approachable, comprehensible, and enjoyable. If I wanted proof writing speed-runs, I'd watch videos by other math UA-camrs, like Math Sorcerer or Wrath of Math.

YES! SHOW US *ALL* THE METHODS!
Very clear..and informative ..Thanks..Cheers
Thank you
Absolute legend. Going over things slowly instead of the other 3 minute videos on YT. Appreciate these videos more than ever man, thank you!
PhD + Old guy with a beard = Proofs!! LOL this is what I thought too! very informative vid!
THANK YOUUU MY CONFIDENCE CAME BACK A LITTLE
Starting it nicely with good 'ol proof methods :)
great stuff, please keep proofing!
Good videos man
Hi saw you on Giilian Perkins channel! Good work!

xRiccardo - i plan on finishing a series on proofs eventually! Thanks for the positive feedback!

Awesome! Glad I could help :)
thank you so much for this!
“I am stupid “ lol. You’re so great bro 😎
Love your content, thanks for taking te time to help someone else.
Great video! Learned a lot. Thanks for such amazing break down

this is great
Thank you very much for making this video. It was very helpful 🙏
Thank you for these amazing lessons! This is awesome , forever grateful😊
Great method
Great Video! Thanks
I'm glad you enjoyed Leo! :D
Good explain and I like your way to tell something Real thanks
first five minutes I could not stop looking at his shoulders
Make a series on numerical analysis
never thought i would study math and laugh at once
Brain Gainz is the best on Proof Writing. Thanks in a MIllion
Your a G thank you
Hello. I'm interested to see how you would prove example 2 by contradiction. Wouldn't it be shorter than a direct proof?
v good
5 star you are the best
Thank u
PLEASE GO ON WITH THE PROOFS PLEASE
What are the Disadvantages of Direct Proof?

More examples pleaaaaaase
14:30 what's my pee and what's my cue 🤨

i like the general content, but i wish you spent less time talking more time doing. i just want to see the problems worked. maybe that's just me

You digress too much.
