AoPS Holidays

There are no classes July 3–5, September 5–7, November 23–29, and December 21–January 3.

Who Should Take?

Students should have a mastery of basic algebra up through and including quadratic equations before taking this course. Typically this class follows our Introduction to Geometry class.

This course goes beyond what you would find in a typical honors Algebra curriculum. Algebra courses vary widely in their definitions, but our Intermediate Algebra class covers topics typically found in honors Algebra 2 and Precalculus classes, as well as many topics that are not found in most other curricula. Students who have completed a typical honors Algebra 2 course elsewhere may be ready for Intermediate Algebra.

Required Textbook

Intermediate Algebra
By Richard Rusczyk and Mathew Crawford

A comprehensive textbook covering Algebra 2 and topics in Precalculus. This book is the follow-up to the acclaimed Introduction to Algebra textbook. In addition to offering standard Algebra 2 and Precalculus curriculum, the text includes advanced topics such as those problem solving strategies required for success on the AMC and AIME competitions.

This was the best math course I have ever taken. I have always been very strong in math and have taken many challenging courses. Intermediate Algebra challenged me at a greater level. Writing problems are the main way that Intermediate Algebra challenged me at a new level. If I had not taken this course, I never would have known the complex proof methods I have learned. The writing problems have also made me more prepared to succeed at contests like the Mandelbrot Competition and the USAMO, as I have learned proof-writing strategies. I always like to know a lot about topics, especially topics that I have a passion for, like math. Intermediate Algebra fulfilled that desire. This was also a great help for preparing for contests like the AMC 12. All in all, this was an excellent course.
