LIII International Mathematical Olympiad (IMO) 2012, Mar del plata - Argentina: problema 1

Estudante brasileiro ganha ouro em competição mundial de matemática IMO2012 ARGENTINA

O estudante Rodrigo Sanches Ângelo, 16 anos, conquistou medalha de ouro na 53ª Olimpíada Internacional de Matemática (IMO). O evento, considerado o mais importante da área pela Unesco foi realizado na cidade de Mar del Plata, na Argentina, reunindo 551 estudantes. Com este resultado o Brasil foi no 19º lugar entre os 100 países participantes.
Além do ouro, o País também conquistou medalha de prata, com João Lucas Camelo Sá. Já os jovens Franco Matheus de Alencar Severo, Rafael Kazuhiro Miyazaki e Henrique Fiúza Gasparini Nascimento ficaram com a medalha de bronze, enquanto Maria Clara Mendes Silva recebeu uma menção honrosa. A equipe brasileira foi liderada pelos professores, Luciano Castro e Carlos Shine.
Realizada desde 1959, a olimpíada se destina a estudantes do ensino médio cujas idades variam entre os 14 e 19 anos e que não tenham ingressado na universidade. Cada país é representado por uma equipe composta por até seis estudantes e dois professores. As provas foram realizadas nos dias 10 e 11 de julho. Em cada dia, os competidores resolveram três problemas, com valor de sete pontos cada, aplicados em quatro horas e meia de prova.
 Os problemas da prova envolveram disciplinas do ensino médio como álgebra, teoria dos números, análise combinatória e geometria. "Os problemas da olimpíada internacional costumam ser mais criativos, não exigindo a aplicação de conhecimentos de matemática avançada, porém, muitas vezes apresentam um alto grau de dificuldade até para matemáticos profissionais", explica o coordenador-geral da OBM, Carlos Gustavo Moreira.
