Ramey Aguadilla, Puerto Rico | September 25, 2019
Ramey Unit School junior Nico was selected as one of four members of the Puerto Rico delegation to the Iberoamerican Mathematical Olympiad. The competition, which was held in Guanajuato, Mexico from September 12-19, involved 92 competitors from Spanish and Portuguese-speaking nations around the world.
The competitors had to complete 9 hours of proof-based mathematical problem solving over 2 days, then defend their solutions to an international jury. At the awards ceremony Nico was recognized with an honorable mention for his solution to the following problem:
"For each positive integer n, such that s(n) is the sum of the squares of the digits of n. Determine all of the values of n>=1 such that s(n)=n."
The Puerto Rico team was comprised of Nico, senior Jorge (Colegio del Espiritu Santo), junior Enrique (TASIS Dorado) and junior Rafael (Colegio Notre Dame). Nico had previously represented Puerto Rico internationally in Cuba and the Dominican Republic, winning silver and bronze medals respectively.
