# Math Jams

Math Jams are free online discussions hosted by Art of Problem Solving for a variety of purposes, including:

- Informational sessions about Art of Problem Solving classes.
- Review of the AMC and AIME competitions.
- Introductions to new topics in math and other areas of study.
- Special events, such as our annual discussions with admissions officers and professors from outstanding universities such as MIT, Carnegie Mellon, Stanford, and Duke.

To attend a Math Jam, simply sign in to Art of Problem Solving just before the Math Jam begins, and click on the Classroom bar that will appear on the screen. The Math Jam classroom will open 10 minutes before the Math Jam begins. (See Classroom System Requirements)

Our Math Jams are held in the same online classroom as our online courses. Click here to read more about how our online classroom works.

Participants in Math Jams must be signed in as Art of Problem Solving Community members to access the Math Jams.

. The Math Jams and Community membership are free.Join our mailing list to receive announcements about new Math Jams.

### North American Computational Linguistics Open Competition (NACLO) Discussion

Instructor: AoPS StaffDifficulty Level: 5* (Intermediate math)

7:30 pm ET

Pranav Krishna will be discussing North American Computational Linguistics Open Competition (NACLO), the national competition for qualifying for the IOL (International Linguistics Olympiad). Problems require participants to decipher the structure of another language, and any central phenomena the problem writer wanted to highlight. While it is only tangentially related to mathematics, there have been those with notable accomplishments in math who have also done well in the NACLO and IOL.

### MATHCOUNTS Practice Competition #3 Discussion

Instructor: AoPS StaffDifficulty Level: 3* (Introductory math)

6:30 pm ET

AoPS instructors will discuss problems from MATHCOUNTS Practice Competition #3, available to registered students on the AoPS Contest Platform. All are welcome!

### Math Without Numbers - Infinity

Difficulty Level: 2* (Introductory math)7:00 pm ET

Is anything bigger than infinity? What about infinity plus one? Guest speaker Milo Beckman, NYC Math Team alum and author of the newly-released book Math Without Numbers, will lead a discussion on one of the most peculiar and surprising topics in modern math: infinite cardinalities. We'll talk about what it really means for a quantity to be "bigger" than another, and use that knowledge to test out some different things that might be bigger than infinity. (And we won't be using any numbers.)

### MATHCOUNTS Practice Competition #4 Discussion

Instructor: AoPS StaffDifficulty Level: 3* (Introductory math)

6:30 pm ET

AoPS instructors will discuss problems from MATHCOUNTS Practice Competition #4, available to registered students on the AoPS Contest Platform. All are welcome!
