QED: MC2's Math Symposium
A citywide showcase where students present original math and computer science projects, explore ideas with mentors, and share their discoveries with the community.

Where Math Meets Curiosity
QED (short for quod erat demonstrandum) is Math Circles of Chicago’s annual math symposium. It is a one-of-a-kind event where students present math and computer science projects they’ve created themselves. From playful puzzles to real-world applications and pure math research, QED empowers young people to think deeply, work creatively, and share their discoveries.
Each December, more than 100 students present their work to judges including math professors, graduate students, and educators. Participants get the chance to earn recognition, win prizes, qualify for the City STEM Fair, and connect with mentors who can guide their future studies.
Many QED students participate in the Illinois State Science Fair, and a few have been Regeneron Finalists!
Real-World Experience
Students tackle problems they care about, develop original solutions, and present their findings—just like professional researchers and scientists.
Mentorship & Support
MC2 connects participants with mentors, resources, and workshops to help them develop and refine their projects.
Recognition & Opportunities
QED participants earn visibility for their work, gain confidence as problem-solvers, and can advance to city, state, and even national STEM competitions.

What do I do if I have trouble coming up with a math idea to research?
Fill out an inquiry form! We are usually able to identify a math graduate student, teacher, or community member with an advanced math background to mentor you and help you come up with a project idea. High School students should join College Pathways and explore the Math
