are often discussed on competitive math forums like Art of Problem Solving (AoPS). : Divisibility, integer solutions, and modular arithmetic
Cuban geometry problems are notoriously challenging. Expect a heavy focus on cyclic quadrilaterals, power of a point, inversion, homothety, and advanced triangle geometry (such as the properties of the orthocenter, incenter, and nine-point circle). Number Theory and modular arithmetic. Involves graph theory
