I always thought like that:

Hmmm: 1 + 2 + 3 + ... + 99 + 100

Kommutativgesetz be like: This equals:
100 +1 + 99 + 2 +98 + 3 . . . And this equals: 101+ 101+ 101+ . . .

How often do I need to do this? I use up 2 numbers for each 101. I have 100 numbers total. So that's 50x101.

Now you can think about: What if it's 1000 instead of 100? But it#s easy from here...

This is why I never succeeded at math. Like why does this shit work?? How can people just take a problem and be like, nah I'm going to just throw numbers all over the place and reassemble them in all sorts of ways and get an answer somehow...

I can't just memorize arbitrary nonsense that "just is" I need to know how it works or it never sticks and all the math I've ever been taught was just "memorize this arbitrary nonsense and regurgitate a specific formula for a specific application that we've spent 0 time explaining other than telling you to memorize it. You want proofs and you can't get proofs until advanced college courses" well guess I'll just never understand mathematical manipulation then...
