달걀의 세계에서 제일 존경받는 수학을 잘하는 달걀 오일라.
어느날 그는 자신의 집에서 껍데기가 깨진 채 발견되었다(달걀의 세계에서 껍데기가 깨졌다는 것은 죽었다는 겁니다)
달걀 경찰인 페로마는 용의자 3명을 찾았고, 각각에게 오일라의 껍데기가 깨질때 무엇을 하고 있었는지 물었다.
1. 에두슨(3주, 달걀 과학자) : 저는 제 실험실에서 여러가지 액체의 산성도를 측정하고 있었어요.
물, 식초, 간장, 글리세린, 위액 등등요.
2. 가오스(3주2일, 달걀 수학자) : 저는 1^2+2^2+3^2+...+n^2이 n*(n+1)*(2n-1)/6 임을 증명하고 환호성을 지르고 있었습니다.
3. 퐈이(1주5일, 일반 달걀) : 저는 공원에서 제 친구 류트와 놀고 있었어요. 숫자카드 게임이었는데 흠뻑 빠져서 집으로 오라는 엄마 전화도 못받았죠.
이 중 오일라의 껍데기를 깨트린 달걀은 누구인지 구하고, 그렇게 생각한 이유를 적으시오.

일단은 정답요청을 안하셔서 제가 정답확인을 못해드리고요.
정답을 쓰실때는 비댓으로 달아주셔야 합니다.
그리고 에두슨은 범인이 아닙니다.
