수학동아 - 폴리매스
[잡담] 여러 예시를 던져주고 기호를 알아내라는 문제

제목처럼 매스펀에 저런 문제가 꽤나 보임미다.
같은 유형의 문제로 매스펀을 계속 도배하는 것도 문제이지만,
이런 유형의 문제는 예시를 만족하는 기호의 뜻을 만족하는 기호연산이 무수히 많이 존재하여 답이 정해지지 않는다는 것임미다.
예를 들어 7~3=0
6~4=0
5~1=?
이런 문제가 있다면 이 문제는 7과 3을 넣었을 때 0이나오고 6과 4를 넣었을 때 0 이 나오는 무한히 많은 3차원 함수에 대해서 성립하기에 물음표에 들어갈 것은 아무것이나 다됩니다. 그에 맞춰서 함수를 끼워맞추면 되기 때문이죠.
자제해주세여

제가 많이 냈다는 것을 인정하고 가끔씩 내겠습니다. 하지만 저는 문제에서 답만 쓰신 분께는 규칙을 요청드렸으니 그냥 아무거나 다 된다고 할 수는 없을 것 같습니다.

답이 여러 개 나오는 문제는... 그걸 모두 다 찾으라는 문제 외에는 별로 좋은 문제라고 볼 수는 없을 것 같습니다...
그런데 규칙 문제는 답을 모두 찾는다는 것이 현실적으로 불가능해서...

ㄴㄴ. 그런 문제는 아무것이나 답이 될수 있습니다. 왜냐하면 함수를 그 답에 따라 끼워맞추면 되기 때문이져
예를들어 님이 만드신 문제를 예로 든다면
7##=153
5##=119
6##=119
를 만족하는 ##는 무한히 많습니다.
8##=1000000000000000000000000000000000000000000으로 해도 만족하는 ##를 찾을수 있다는 거죠
