어떠한 자연수 N에 관하여, 1과 함께 적당한 사칙연산(그리고 괄호)을 가하면 자연수인 수 M이 된다고 하자.
이때 M을 N과 1들에 관한 식으로 나타낸다.
예를 들어, N=2, M=15인 경우에는 M=(N+1+1+1+1+1+....+1)=(N+1+1+1)(1+1+1)과 같이 다양한 방법으로 나타낼 수 있다.
이러한 연산 중 사용하는 1의 수가 가장 적은 연산을 '어몽 연산'이라고 하자.
N=4, M=67일 때 어몽 연산에 N = 1, M = 1을 대입하였을때 값은?
(혹은 이러한 어몽 연산을 구하는 특정한 방법이 있음을 증명/반증하여도 정답처리)
