The American Invitational Mathematics Examination (AIME) is a mathematics competition for high school students in the United States. It serves as a qualifying exam for the USA Mathematical Olympiad (USAMO) and is typically held annually in March. The AIME consists of 15 multiple-choice questions, each worth 1 point, and students have 3 hours to complete the exam. Participants must score well on the American Mathematics Competitions (AMC) 10 or AMC 12 to qualify for the AIME. The questions cover various topics in mathematics, including algebra, geometry, and number theory, and are designed to challenge students' problem-solving skills.
