Below are all previous MOAA competitions, sample problems, and solutions. Note that the sample problems and sample solutions are bundled into one document.
MOAA 2026
MOAA 2026 was held both in-person and virtually and consisted of four rounds: Speed Round, Accuracy Round, Team Round, and Gunga Bowl. Every problem on each round was solvable and computationally feasible with middle school mathematical techniques; no calculators or computational aids were necessary for any problem.
MOAA 2025
MOAA 2025 was held both in-person and virtually and consisted of four rounds: Speed Round, Accuracy Round, Team Round, and Gunga Bowl. Every problem on each round was solvable and computationally feasible with middle school mathematical techniques; no calculators or computational aids were necessary for any problem.
MOAA 2024
MOAA 2024 was held both in-person and virtually and consisted of four rounds: Speed Round, Accuracy Round, Team Round, and Gunga Bowl. Every problem on each round was solvable and computationally feasible with middle school mathematical techniques; no calculators or computational aids were necessary for any problem.
MOAA 2023
MOAA 2023 was held both in-person and virtually and consisted of four rounds: Speed Round, Accuracy Round, Team Round, and Gunga Bowl.
