United States of America Mathematical Olympiad

The United States of America Mathematical Olympiad (USAMO) is an invitation-only mathematical competition sponsored by the Mathematical Association of America and hosted by the University of Nebraska-Lincoln. It is a 2-day event in which the contestants try to give proofs to six mathematical problems. The judges award 0 to 7 points to each solution, thus a perfect score is 42 (http://planetmath.org/FortyTwo) points. The winners go on to represent the United States in the International Mathematical Olympiad. Currently, the Internet is used to present the problems the first day of the competition; on the second day the contestants fax back their answers.
