수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
위 사진에 나오는 86-33=95라는 잘못된 식에서 성냥개비를 두 개만 옮겨서 올바른 식을 만들어 보자.
단, 이때 등호는 건드릴 수 없고, 십의 자리 수가 0이 될 수는 없다.
그리고 이 퍼즐은 답이 적어도 3개 이상 나온다. 그래서 이 식을 고친 예를 서로 다르게 3개 이상 만들어 보자.
(추신: 혹시라도 이 문제가 단순문제로 오해받으면 죄송합니다. 하지만 이 문제는 제가 직접 만든 것으로, 이 문제를 내기 위해 몇십 분을 고민했습니다. 이 문제가 너무 성의없는 문제라고는 생각하지 말아 주시기 바랍니다.)
체점 기준: 1개만 쓰면 오답 처리, 2개를 쓰면 부분해결, 3개 이상을 쓰면 해결 처리
