Los Angeles Math Circle

Welcome to the Los Angeles Math Circle (LAMC)!

Spring quarter session 2019

We are accepting applications for Spring 2019 at the moment. If you are new to the math circle, please read FAQs first.  More Spring 2019 info.

Continuing students in good standing are guaranteed a spot in the Spring session (need to apply by 4/5/19).

New students: Please start by going over our FAQs addressing the enrollment process. The next opportunity for new students to apply is Summer session 2019. Information and applications will be available on this web page in May 2019. All applicants will have to take an assessment in late May -- early June. 

If you decide to apply for Spring session (with the understanding that the chances of a spot opening up are very small), please fill out your application in details providing all the required information. Please also note that applications do not roll over. If you apply for one session and are not admitted, you need to apply again for the next one. This is the only way for us to know that you are still intereseted. 

For now, please feel free to use our curriculum at home. Handouts are posted weekly and are available in the "Calendar" section of the web page. Handouts from past years are available in the "Archive" section of the web page.

Jack Fasching (7th grade)

We wish all of our AMC8 participants future successes in their math journey.


Coming up next weekend:

4/21 -- Beginners: Knights, Knaves and Knormals.

Logic puzzles are a mainstay of recreational mathematics, and today we'll be solving problems involving people that always tell the truth (knights), always lie (knaves), and sometimes tell the truth and other times lie (knormals). Solving these problems can be challenging, but we'll learn how to approach them is a systematic way so that you can always find the answer. Although these problems seem like all fun and games, they actually have some connections to mathematical logic; the most fundamental branch of modern math.

4/21 -- Early Elementary I: Odd and even numers (Oleg Gleizer)

We will study odd and even numbers in the decimal and binary form.

4/21 -- High School I: Introduction to Groups I

We introduce the definition and basic properties of a group in the context of the symmetries of a square index card in the plane.

4/21 -- High School II: Expected number of hacky sacks and temper tantrums (Paul Zeitz)

Watching a math circle for 2nd and 3rd graders leads to nontrivial questions about probability and expected value. We will discover interesting and non-intuitive phenomena about randomness.
