NanoMath Winter Championship

January 30, 2021

A student-run online math competition and event for high school and advanced middle school students. In addition to contest rounds, we also have various activities.

This contest will be a partial re-run of the ASDAN Math Tournament, a math contest in China with 750+ participants with problem writers from Berkeley/BMT, Stanford/SMT, JHU/JHMT, Princeton/PUMaC, etc.

Our goal is to make mathematics beyond the school curriculum accessible to more people and promote the collaborative nature of math.

Activities include an estimathon, a guest lecture by Simon Rubinstein-Salzedo, director of Euler Circle, as well as other notable mathematicians.

Our organization previous hosted the Fall Math Meet in October 2020, where over 250 students competed live.

Frequently Asked Questions

Who can attend the contest?

Any student aged 18 or under and who has not started college is eligible to attend the Winter Championship. However, problems are written at a high school level. For questions about eligibility and exceptions, please email us at Students outside of the U.S. are welcome to compete and receive digital prizes such as gift cards, but are not eligible to receive physical prizes to logistical reasons.

Will there be activities besides the contest?

Yes! There will be talks by notable mathematicians, as well as other activities.

Who may be on a team?

A team consists of three competitors. Students do not have to be from the same school in order to be on a team.

What should I do if I do not have enough people to form a complete team?

If you do not have a complete team, we can help you find other teams to pair up with. You can also compete with an incomplete team; however, you will be at a disadvantage.

What materials are allowed on the contest?

We follow the same rules as AMC and AIME. The materials allowed are rulers, straightedges, compasses, and graph paper. Calculators are not allowed, and computers should only be used to communicate during team rounds.

What topics may appear on the tests?

The topics covered are Algebra, Geometry, Number Theory, and Combinatorics. You can view some sample questions here. Note that sample questions may not be indicative of test difficulty.

How hard are the tests?

For those familiar with math competitions, the difficulty of the tests ranges from early AMC to late AIME problems. You can view some sample questions here. Note that receiving what might be considered a "passing" grade in school will be rather difficult, so don't be discouraged if you don't.

How will the contest be held?

The contest will be held live over Zoom on January 30, 2021. The link will be sent out shortly before the contest date.
