수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
[창의 퍼즐] [창의/조합]폴리와 매스의 수식놀이
폴리와 매스가 탁자에 마주보고 앉아 수식놀이를 한다.
디지털시계 기준 모양으로 1~9가 적힌 카드가 1장씩 총 9장이 있는데, 폴리는 이 카드들 중 3장을 사용하여 (두자리수)×(한자리수)의 수식을 만든다.
이때, 매스는 폴리와 맞은편에 앉아 있으므로 폴리가 만든 수식을 180°회전된 상태로 보게 된다.
폴리가 본 수식의 값과 매스가 본 수식의 값이 같게 되는 경우는 몇가지가 있을까?
풀이과정과 답을 구해보자.
