Math Day at the Beach 2022 Winners

Published March 18, 2022

Math Day at the Beach is a problem-solving festival for Southern California high school students who want to have fun with mathematics and enjoy a day of camaraderie with university mathematics students and professors.

This annual event started in 2002 by the Department of Mathematics and Statistics under the directorship of Dr. Kent Merryfield, a charismatic leader with unparalleled expertise in high-school math competitions, and ran uninterrupted until Dr. Merryfield's untimely death in November of 2018. In March of 2019, the 20th Math Day at the Beach took place under the new directorship by Dr. Olga Korosteleva. Then the pandemic placed this event on hold for two years.

On March 12, 2022, the 21st event was hosted on the campus in a restructured format. Its unequivocal success boosted the energy level of the organizing committee members who immediately started planning for the next year. There were three parts to this event: an individual round, team round, and the Kenneth E. Lindgren Face-off round. The problems were designed by the Mathematics and Statistics Department faculty and were selected from algebra, geometry, trigonometry, number theory, combinatorics, and probability and statistics. They emphasize creative thinking rather than computational skill.

Math Day is completely free, thanks to our generous sponsors, the Jerry Cassaday Family and LBS Financial Credit Union.

Invitation to 2023

An invitation to participate in the 2023 event will go out to schools in October of 2022. If your school is interested in trying its hand at tackling those math problems, email Dr. Olga Korosteleva at to request practice tests.
