The AMC 10 and AMC 12 are both question, minute, multiple-choice examinations in high school mathematics designed to promote the development and enhancement of problem-solving skills. The AMC 10 is for students in 10th grade and below and covers the high school curriculum up to 10th grade. Students in grade 10 or below and under The AMC 12 covers the entire high school curriculum, including trigonometry, advanced algebra, and advanced geometry, but excluding calculus. Students in grade 12 or below and under The only differences are the competition dates and that each version has a distinct set of questions, although the two examinations are designed to be equal in difficulty and distribution of topics. Schools can order one or both versions of the tests, so long as they pay the appropriate registration fee for each competition date and purchase the competition bundles for each date. Competition Managers can find all additional forms needed below. We are hosting our statistics through our new platform. Please note that we have amended the information we publicly provide in these statistics for student privacy. The AMC 10 covers mathematics normally associated with grades 9 and The AMC 10 assumes knowledge of elementary algebra; basic geometry knowledge including the Pythagorean Theorem, area and volume formulas; elementary number theory; and elementary probability. What are excluded are trigonometry, advanced algebra, and advanced geometry.

Commencing 2022 amc10a early allows for the establishment of a systematic and comprehensive exam preparation process, 2022 amc10a, ensuring ample time for thorough coverage of all AMC 10 topics. Successfully solving these challenging questions can enhance the overall tolerance for errors in the exam.

Suppose that cards numbered are arranged in a row. The task is to pick them up in numerically increasing order, working repeatedly from left to right. In the example below, cards are picked up on the first pass, and on the second pass, on the third pass, on the fourth pass, and on the fifth pass. For how many of the possible orderings of the cards will the cards be picked up in exactly two passes? For suppose that cards are picked up on the first pass. It follows that cards are picked up on the second pass. Once we pick the spots for the cards on the first pass, there is only one way to arrange all cards. For each value of there are ways to pick the spots for the cards on the first pass: We exclude the arrangement in which the first pass consists of all cards. Therefore, the answer is. Since the cards are picked up in two passes, the first pass must pick up the first cards and the second pass must pick up the remaining cards through.

Isosceles trapezoid has parallel sides and with and There is a point in the plane such that and What is. Consider the reflection of over the perpendicular bisector of , creating two new isosceles trapezoids and. Under this reflection, , , , and. Since and are isosceles trapezoids, they are cyclic. Using Ptolemy's theorem on , we get that , so Then, using Ptolemy's theorem again on , we get that , so Thus, and ; dividing these two equations and taking the reciprocal yields.

If mastering the must-do problems is the foundation for success, then not losing points on easily mistaken questions is the key to achieving AIME qualification. Who can proctor the competition? We can rationalize this fraction to get. We can proceed by casework on the number of distinct digits in the string. Over the long term, students are encouraged to expand their knowledge beyond their regular coursework, focusing on addressing their mathematical weaknesses during summer breaks, particularly the summer preceding their dedicated exam year.
