>>12064980That's a tough question. It's something I'd want to restrict to exclusively the greatest theorems, which for me would require some criteria, such as:
1. Comfy (Intuitively correct)
2. Useful (Widely applicable)
3. Big (fairly general case)
Bonus points for a clever proof.
I'm definitely missing some criterion here, but that would be some of the big ones. If I were to give some examples of 10/10 theorems, I may suggest ones such as: Any of the "fundamental" theorems, the Jordan curve theorem, Abel-Ruffini, etc
I am more of a fan of Algebra, so I'm sure I'm missing some great theorems in number theory and analysis, but these are just options. Some of these might fall more into the 9/10 category, and honestly I could easily bump Bolzano-Weierstrass one and not lose any sleep
