최소 개수의 성냥개비를 옮겨서 위 두 등식이 성립하게 만들어라.

 

조건.

1) 두 등식은 별개의 문제로 취급한다. 즉, 한 문제에서 다른 문제로 성냥개비를 옮길 수 없다.

2) 위 그림에서 = 기호(등호)에서 성냥개비를 제거하거나, 성냥개비를 추가해 \neq로 만들 수 없다.

 

한 문제만 맞으면 부분 해결, 두 문제 모두 맞으면 해결입니다.

이 문제 어떠셨나요?

글쎄요

      1번 소문제 맞았습니다.

      2번은 조금만 더 고민해 보세요!

      2번은 맞습니다.

      1번은 조금 억지인 것 같습니다.
