수학동아 - 폴리매스
함께 풀고 싶은 문제
나도 수학쌤 문장제 문제를 변형해 문제를 내는 곳입니다.

*이 시리즈는 이제 스토리로 이어집니다
당신이 수포자가 된지 벌써 3년하고도 반이 되었습니다
당신은 수학책을 보다 미적분을 공부하다 수학을 포기하게 되었습니다
지금부터 당신의 수포기운을 빼고 수학을 성공하게 만들어드릴것입니다
그래서 먼저 당신이 어떤 레벨에서 수학성공을 할수 있는지 테스트를 먼저 해야되겠군요
레벨테스트를 하겠습니다
1번과 2번문제를 모두 맞으면 당신은 레벨 3에서 시작할 수 있고
2번만 맞으면 레벨 2,
1번만 맞으면 레벨 1
아무것도 못맞추면 레벨 0 부터 시작합니다
이제 문제 나갑니다
1) 당신은 디지털시계를 보고 있습니다. 당신이 사는 세계는 10시까지밖에 없고, 1시간이 30분입니다
시계가 현재 n시 m분을 가르키고 있군요
어느덧 n+x시 m+nx분 이 되었습니다
그러면 모든 쌍 (n,x,m)의 개수는 몇개일까요?
2) 당신은 달력을 보고 있습니다
어느덧 달력의 연도의 각 자릿수의 합이 아까 그 디지털시계의 n시입니다
그리고 또 오늘의 달과 날을 이어붙인 수의 각 자릿수의 곱이 m이군요
그러면 모든 쌍 (n,m) 는 몇개일까요?
