Cuban problems rarely require calculus. They focus on:
Here is the PDF related to Cuban Mathematical Olympiads: cuban mathematical olympiads pdf
For example, a classic Cuban problem might ask: Cuban problems rarely require calculus
"Find all integer solutions to $x^3 + y^3 = (x+y)^2$ using modular arithmetic and the properties of prime factorization." " if possible. For example
Maybe add a section on "Notable Cuban Mathematicians and Their Olympiad Backgrounds," if possible. For example, if any prominent Cuban mathematicians started in olympiads. However, without specific names, this might be speculative.
