Researchers have developed a neural theorem prover that can solve certain formal math problems. The system uses Lean, a proof assistant language, and has been trained on high-school level olympiad problems from competitions like AMC12, AIME, and IMO. It was able to solve several challenging problems in these areas. --- Why it matters: This matters because it demonstrates the potential for AI to assist in formal math problem-solving, which is a key area of research in mathematics education.
