Welcome to Euler Circle!

Note: Euler Circle will be held online in the spring quarter. We are reopening applications until March 18th. You do not need to live in the San Francisco Bay Area to attend online classes.

Are you a high-school student in the San Francisco Bay Area who loves mathematics? Do you find the traditional mathematics curriculum far too easy? Do you want to learn fascinating and challenging mathematics? Do you want to work on problems and make friends with mathematically-minded peers? If so, you have come to the right place!


Euler Circle is a mathematics institute for advanced students in the San Francisco Bay Area who love mathematics. We offer a range of college-level mathematics classes, specifically tailored to the needs of advanced high-school students, many of whom have exhausted the mathematics curriculum at their schools and want to learn more. Each class we offer is the equivalent of a college mathematics class. In each class, students solve many problems to gain familiarity with new material, and in the advanced classes each student writes an expository paper on a topic related to the class material.

The classes are set up in such a way as to provide a pathway to independent research. Many of our problem sets in the advanced classes include unsolved problems that students can explore once they have mastered the material presented in class. We offer small group meetings for students interested in working on the research problems once they have demonstrated the ability to work hard on challenging problems. See more on research in Euler Circle.


There is more to mathematics than competitions. Yet there are few resources available for high-school students to learn about the rest of the wonderful world of mathematics. We believe that many students would like to see what else is out there, and we want to share what we know.


Advanced classes meet for four hours a week. They are held on Tuesday and Wednesday evenings from 6:30–8:30 PM at the Cubberley Community Center in Palo Alto. Our next class (in Spring 2020, starting at the end of March) will be on abstract algebra. See a description of the course.

Intermediate classes meet for three hours a week. They are held on Monday evenings from 5:30–8:30 PM, also at the Cubberley Community Center in Palo Alto. These are classes on proof techniques and mathematical writing, and they will help students learn how to transition from numerical answer problems to proof-based mathematics. In the winter, the topic will be analysis. See a description of the course.

Although the official application deadline has passed, it may be possible to accept a few more students on a first-come first-serve basis. Click here to apply!
