The statement "2 is the only even prime number" sounds unusual at first... But if I consider the definition of "even" as "divisible by 2", then I reach the conclusion that "2 is the only prime number divisible by 2". And... of course it is. If any other number were divisible by 2, it would not be prime.

So, we can say that for any prime number n, n is the only prime number divisible by n. For example, 3 is the only prime number divisible by 3. One could say that "3 is the only threeven prime number". Is that unusual? Perhaps not.

A question for the reader, then - why do we consider "odd" and "even" to be special properties?

Math in development

As someone who bombed out of Dutch Middle School and had to finish the adult equivalent at like 16-18, never picked up math again and got into development through a bootcamp, I have not found a lot of application for more complicated math subjects yet, outside of like complicated katas (there I tended to just look up the right equation and implement it), but I also feel very... I dunno, it seems Useful To Know but most of the more complicated implementations have been abstracted away most of the time and a lot of your day-to-day will not involve that, although I wonder if it is more present in more low-level applications.

I have complicated feelings about it because I feel like it would be very useful to me to know and fun to know both (I think I could be very good at it. I seem to genuinely enjoy it), but I am also Older Now and I have neither the money nor the time to go back and study basic math all the way to university math just to do the job I'm already doing. Learning gets increasingly more fraught when you get older and academia is a scam.

Lately, I feel like I can’t do any math proofs without help (in algebra)

There are few things in math I hate. My top op has and will always be completing the square. I’ve hated that bitch since seventh grade and I felt so free, so elated when I finished that unit and grade and decided I’d never have to do that again. SO TeLL me Whyyyuyuyyyuuy I get to the end of this Fourier transform AND I HAVE TK COMPLETE THE SQUARE. TAKE THIS SHIT OUT OF MY QUANTUM MECHANICS T A K E I T O U T. I literally refused to finish an integral on my final wrote im not doing this shit that is how much I haaaaaate that stupid technique. Fuck completing the square

If you think about it, 0 is the black hole of the mathematical world. And unlike real life black holes, nothing escapes it's grasp. Even reality breaks when you get near it.
