Mathematics for Adults

Real math. The visual, intuitive kind that finally clicks.

From linear algebra you actually understand to number theory that doesn't require a PhD. The cure for being told 'just memorize it' once too often.

Curation rubric (what the LLM is told to look for)

Reward: visual intuition, multiple representations, historical context for why a result matters, derivations over assertions. Penalize: cram-school exam prep, generic puzzle clickbait, calculator demos.
