The contest problem book:

Over the years perhaps the most popular of the MAA problem books have been the high school contest books, covering the yearly American High School Mathematics Examinations (AHSME) that began in 1950, co-sponsored from the start by the MAA. Book V also includes the first six years of the American Invitational Mathematics Examination (AIME) which was developed as an intermediate step between the AHSME & the USA Mathematical Olympiad (USAMO). The AIME has a unique answer format - all answers are integers between 0 & 999. New material, not included in premenu contents books is: * a comprehensive guide to other problem materials world wide, * additional solutions, * dropped problems, * statistical information, * information on test development & history. This volume is a must for avid fans of elementary problems. Contest Books I-IV appear as NML volumes 5, 17, 25, & 29. See below.
