As I remember it they had solutions to all forms of quadratics, systems of linear equations, reciprocals, 3D reasoning, simple cubics, etc... and all in natural language formulations, rhetorical algorithms. This meant, unfortunately but inevitably, land area calculations, agricultural product apportionment/taxation, and compound interest calculations were enumerated exhaustively for each type of grain, etc... that is a lot of clay tabletage which today could be superceded by a very thin pocket reference today.<o:p></o:p></p><p>Of course Aristotle's logics and the work of other famous Greeks like Archimedes began to create some 'reserved formal language' still in use today. Russel and Whitehead's <i>Principia Mathematica </i>was an astounding body of work in formalization to be undermined at it's foundations by Godel's <i>Incompleteness Theorems. </i>Of course, the real mathematical wonks here know of roughly a dozen major fields of Mathematics not covered by or alluded to in Principia Mathematica. <o:p></o:p></p><p>I can't say one way or another how well this work PC + post PC math can be described by natural language.

They have also helped me with the illusion that I understood the philosophical implications of things, but I think Glen's point might be on point... I'm not sure that what I'm getting from these LLMs is more than a (strong) gist and gesture in the right direction. On the other hand I think LLMs *can* and *do* train on and manipulate effectively formal language constructs (such as logic and mathematics in general)... and coupled with huge amounts more training on natural language can express something a lot like intuition about mathematical statements.<o:p></o:p></p><p>The more I rattle on here, the more I realize I'm out of my depth... something I can often get an LLM to state for itself but I don't actually believe it, I think it is just trying to please me?<o:p></o:p></p><p><o:p> </o:p></p><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal><br>On 4/29/25 10:09 AM, Marcus Daniels wrote: <br><br><o:p></o:p></p><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal style='margin-bottom:12.0pt'>If natural language didn’t work, people wouldn’t publish papers, they’d publish math and computer programs. <br><br>In any case, it is all the just different kinds of patterns.
