# Math Challenge II-B

### Course Description

In Math Challenge II-B, students learn and practice in areas such as algebra and geometry at the high school level, as well as advanced number theory and combinatorics. Topics include polynomials, inequalities, special algebraic techniques, trigonometry, triangles and polygons, collinearity and concurrency, vectors and coordinates, numbers and divisibility, modular arithmetic, residue classes, advanced counting strategies, binomial coefficients, pigeonhole principle, sequence and series, and various other topics and problem solving techniques involved in math contests such as the American Mathematics Competition (AMC) 10/12, ARML, and also beginning AIME.

### Course Textbooks

Each term requires the course textbook:

The textbook is available in print on our online bookstore (click here) or eBook on redshelf.com (click here).

### Course Terms

Math Challenge II-B is offered in four terms:

- Summer, covering Algebra
- Fall, covering Geometry
- Winter, covering Combinatorics
- Spring, covering Number Theory

We recommend that students take all four terms, but the terms do not build on previous terms, so they do not need to be taken in order and students can take single terms if they want to focus on specific topics. For more information about the topics covered each term, please click here.

### Course Meetings

This course meets Saturdays 10:45 AM-12:15 PM Pacific (1:45-3:15 PM Eastern). For the specific dates of the course please see the full course schedule by clicking here.
