## About this program

# CrowdMath

CrowdMath is an open, collaborative mathematics research project run jointly by MIT PRIMES and Art of Problem Solving, inspired by the professional Polymath projects. Each year a new set of open questions is posted - the 2026 project is 'Arithmetic Conjectures on Rational Semirings' - and participants work together in moderated AoPS forums, guided by research mentors, toward results that have in past years become collaborative papers with all contributors credited.

## What You'll Do

- Study the posted resources - background reading chosen to build exactly the tools the project needs
- Attack genuinely open problems: 'The problems in the CrowdMath project are open, unsolved problems in mathematics'
- Post partial arguments, find and repair gaps in others' reasoning, and synthesize progress with collaborators worldwide
- Work with research mentors who steer the discussion, with publishable results written up jointly

## Who Should Apply

CrowdMath 'gives all high school students the opportunity to collaborate on a large research project with top-tier research mentors' - college students may also participate. Realistically it suits students with very advanced backgrounds (olympiad experience or university-level coursework) who want authentic research without leaving home; you simply register on the Art of Problem Solving site and start contributing.

## Outcomes

Participants get real research experience - reading literature, making conjectures, proving lemmas in public - and meaningful contributors have been credited on resulting papers. It is one of the only ways for a high schooler anywhere to do mentored, publishable mathematics research year-round.
