一位大学数学教授和他妻子都已经60岁了。

一天晚上，妻子回到家，看到丈夫留下的一张纸条，上面写着：“亲爱的，你现在已经60岁，有些事情你不再为我做了。我现在假日酒店，和我的一位20岁学生在一起。别等我了。”

当晚，他很晚才回到家里，看到了妻子留下的一张纸条：“你，我亲爱的，也60岁了，也有些事情是我需要的而你却给不了我。所以我现在6号汽车旅馆，和你的一位20岁学生在一起。你作为一位数学教授，我相信你一定知道60除以20多于20除以60。所以，别等我了。”

A Math Professor's Mistake

A college math professor and his wife are both 60 years old.

One evening the wife comes home and finds a note from her husband that says, "My dear, now that you are 60 years old, there are some things you no longer do for me. I am at the Holiday Inn with my 20-year-old student. Don't bother waiting up for me."

He returns home late that night to find a note from his wife: "You, my dear, are also 60 years old and there are also things I need that you're not giving me. So I am at the Motel 6 with one of your 20-year-old students. Being a math professor, I'm sure you know that 20 goes into 60 way more than 60 goes into 20. So, don't you wait up for me."
