USAMO Problems and Solutions

The United States of America Mathematical Olympiad (USAMO) is a highly selective high school mathematics competition held annually in the United States.

The United States of America Junior Mathematical Olympiad (USAJMO) was introduced in 2010 to recognize top scorers based on their AMC10-based index. Qualifying for the USAMO is considered one of the most prestigious awards for high school students in the United States. Top scorers on the USAMO are invited to the Mathematical Olympiad Summer Program to represent the United States at the International Mathematical Olympiad.
