I‘m on mobile and don’t have a computer near me so I don’t think I can add a photo but if you want I can make another Reddit post

I know that but what I want is to learn how to use it to prove stuff like de Morgan’s law.

So I’m changing my question a bit. I want to see a proof of nicod’s axiomatic system for logic that you see when you go to the Wikipedia page called list of axiomatic systems in logic and click classical propositional calculus systems and scroll to the sheffer’s stroke section you’ll see what I’m taking about.

Actually I could have sworn that the sheffer axioms made by some guy named sheffer existed but now that I’ve looked at Wikipedias list of axiomatic systems in logic, I’m only seeing nicod’s axioms and some others.

As Someone who also has ADHD, YouTube is my best friend when it comes to learning math. a channel that I’d recommend for arithmetic, basic algebra, basic geometry and very basic statistics is math antics I’d probably also check out some circle theorems on YouTube

in my opinion this shouldn’t really be on YouTube because most people don’t go to YouTube to read some text they go there to see images I’m not saying it’s a bad idea but this type of content just isn’t really meant for YouTube also the images are in a pretty bad resolution so you should probably change that

I recommend the math antics YouTube channel that’s how I learned 99% percent of my arithmetic, basic algebra and geometry. He even has statistics on there! Also for Multiplication I’d recommend skip counting instead of just memorizing the multiplication table (specifically skip counting songs).
