Metamath

Metamath is a formal language and an associated computer program (a proof checker) for archiving, verifying, and studying mathematical proofs. Several databases of proved theorems have been developed using Metamath covering standard results in logic, set theory, number theory, algebra, topology and analysis, among others. As of February 2022, the set of proved theorems using Metamath is one of the largest bodies of formalized mathematics, containing in particular proofs of 74 of the 100 theorems of the "Formalizing 100 Theorems" challenge, making it fourth after HOL Light, Isabelle, and Coq, but before Mizar, , Lean, Nqthm, ACL2, and Nuprl. There are at least 19 proof verifiers for databases that use the Metamath format. This project is the first one of its kind that allows for interactive browsing of its formalized theorems database in the form of an ordinary website. (Wikipedia).

High Stakes Maths: Aliens, metamath, Wolfram Problem Generator, 5 + 4 = ?????

This is a video about a scifi scenario in which it would make sense to rigorously prove 5+4 all the way from the ZFC axioms using metamath. It's massively over rigorous overkill for a simple and basic problem, which is kind of the motto of pure mathematics haha. I hope this series is an
