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.

Coming up next weekend:

4/28 -- Advanced: Combinations IV

This week we introduce the binomial formula, and the "stars & bars" counting strategy.

4/28 -- Beginners: Divisibility

This weekend we'll be talking about divisibility. Just about everyone knows what it means to divide two integers, but this week we be doing almost no dividing. Instead we will be a lot more concerned with the question of when two one integer evenly divides (i.e. has no remainder after division) another. Divisibility might not sound like a terribly deep or nuanced topic, but it is, in fact, more nuanced and developed than you would believe. Further, it is a common entry into talking about abstract algebra, one of the largest branches of modern pure math.

4/28 -- Early Elementary I: Odd and even numbers, continued. (Oleg Gleizer)

We will continue to study odd and even numbers in the decimal and binary form. If time remanis, we will do a bit of magic related to binary numbers.

4/28 -- High School II: Wallpaper Patterns

What kinds of patterns can be used as wallpaper. What are their groups of symmetries, and how can we classify them? How many are there? We will attempt to answer some of these questions and learn how to categorize wallpaper patterns.
