(Rated Easy) The first problem involved a geometry scenario with a triangle and a perpendicular foot. It required basic area and Pythagorean theorem applications. The final answer was a three-digit integer (e.g., 252). Most students found Problem 1 straightforward, setting a calm tone for the exam.
To score a 10 or higher (which in 2013 virtually guaranteed a USAJMO or USAMO invitation), students had to crack at least one of these final five problems. The is famous for its Problem 14. 2013 aime i
In the world of competitive mathematics, few events carry as much weight and prestige as the American Invitational Mathematics Examination (AIME). Bridging the gap between the high-volume AMC 10/12 and the elite USA Mathematical Olympiad (USAMO), the AIME is a 15-question, 3-hour examination that tests not just knowledge, but ingenuity, patience, and computational stamina.
