수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
1+1=귀요미, 2+2=귀요미이면 왜 안 되는지 증명하여라.

제가 생각하기엔 이 문제는 문제로 낼 내용이 아닌 것 같습니다.
기사로 낼 예정이니 확인해보세요

<기사 내용>
생활속에서 1+1=귀요미! 2+2=귀요미!... 하면서 자신의 귀여움을 나타내는 사람들이 있다.
하지만 수학적으로는 이것이 성립하면 큰일난다.
그 이유를 지금부터 살펴보자.
일단 1+1=2+2가 되므로, 2=4가 된다.
양변에 2를 나누면 1=2가 된다.
앞서 계산한 식에 따라 1=2=4가 된다.
1=4에서 양변에 1을 더하면 2=5, 1을 빼면 0=3이 된다.
2=4에서 양변에 1을 더하면 3=5가 된다.
따라서 0=1=2=3=4=5이다.
4=5에서 양변에 1씩을 계속 더하면
5=6, 6=7, 7=8, 8=9...과 같이 모든 자연수가 같아진다.
0=1에서 양변에 1씩을 계속 빼면
-1=0, -2=-1, -3=-2, -4=-3...과 같이 모든 음수도 같아진다.
결국 1+1=귀요미, 2+2=귀요미이면 모든 정수가 같아진다.
그래서 1+1=귀요미, 2+2=귀요미이면 이 세상이 사라질 수도 있다.
