Yesterday, select middle school and high school students participated in this year’s AIME I Competition (including some students proctored by Areteem online).
The problems can now be discussed! See below for the answer key for the 2022 AIME I questions as well as the concepts tested on each problem. All answers for the AIME are in the form of 3-digit integers.
algebra: quadratics, equations, and logic
number theory: bases and digits
geometry: trapezoids, angle bisectors, and similar triangles
algebra and number theory: complex numbers, polar form, and modular arithmetic
algebra and geometry: motion, vectors, equations, and relative speeds
algebra and combinatorics: sequences, counting, and careful thinking
algebra and number theory: cases, substitution, and minimums
geometry: triangles, circles, and tangents
combinatorics: counting, careful thinking, and permutations
solid geometry: spheres, cross-sections, and distance formula
geometry: parallelograms, circles, and power of a point
combinatorics: sets, counting, sums, and combinatorial identities
number theory and combinatorics: repeating decimals and counting multiples
geometry and number theory: triangles, polynomials, and Pythagorean triples
algebra: geometric interpretations and trigonometric substitutions
Want to practice more AMC and AIME Problems? Check out the Zoom International Math League (ZIML) practice page here for practice resources, including Mock Exams and old Exams.
The AIME I exam is administered by the Mathematical Association of America (MAA). Students are invited to take the AIME based on their scores for the AMC 10 and 12 exams. For general information about the AMC 10 and 12, click here.
