Participants had to find prime numbers and an integer satisfying the equation

A significant majority (24 out of 28) of gold and silver medalists achieved a perfect score on Problem 1, confirming its low difficulty.

. Commentary suggests this was a very accessible problem, possibly even at a 5th or 6th-grade level, which resulted in a high number of maximum scores.

for positive real numbers. The minimum value was found to be 3.

Problem 3 (Geometry) was noted for its "attackability" through multiple different methods, including classic Euclidean geometry, vectors, and coordinate geometry.
