A language and a proof verifier for developing formalized mathematical proofs.
Metamath is a language and a proof verifier for developing and verifying strictly formalized mathematical proofs, bundled with collaborated databases containing thousands of proven theorems including conventional results in logic, set theory, number theory, group theory, algebra, analysis, topology and various other topics. All proofs are in the form of Hilbert-style formulas.
