수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
우박수 활동은 다음과 같은 규칙을 반복하여 1이 되게 하는 활동이다. 규칙은 다음과 같다.
| 1. 자연수 하나를 선택한다. |
| 2. 짝수면 2로 나눈다. |
| 3. 홀수면 3을 곱한 뒤 1을 더한다. |
jun은 이를 변형하여 다음과 같은 규칙을 만들었다.
| 1. 1을 제외한 자연수 하나를 선택한다. |
| 2. 홀수 또는 6이면 4로 나누고 몫과 나머지를 곱한다. |
| 3. 짝수 또는 3이면 2를 곱하고 1을 뺀다. |
1. 위 규칙을 적용했을 때 모든 자연수가 위 규칙대로 1이 되는가? 아니라면 반례를, 맞다면 근거를 드시오.
2.여러분도 위와 같이 우박수 변형 문제를 만들어 보시오.
그 대신 조건은 위와 같이 세 개의 단계로 이루어져 있고, 1부터 30까지 자연수는 무조건 다 적용되야 한다.
단순문제라고 생각되시면 문의 부탁드립니다. 풀이는 필수입니다!❤
