有一个英文老师出了一道这样的难题,题目是这样子的:
____ is better than the god.
____ is worse than the evil.
if you eat ____,you will die.
(三个空格必须是同一个字)
没有人答的出来
结果......
有一个数学老师用数学的方法解出来了 :
设上帝之善是+∞ 恶魔之恶是-∞ 令所求为x 则x>+∞
x<-∞
∴x属於空集合
∴x=nothing
answer:
nothing is better than the god.
nothing is worse than the evil.
if you eat nothing, you will die.
