Pure Mathematics 18 n 54      Hi you men out there use your Maths next time...................                A husband wrote the following letter to his wife and left it on the dining room table:  “My Dear Wife,  You will surely understand that I have certain needs that you, being 54 years old, can no longer satisfy.  I am very happy with you and value you as a good wife.  Therefore, after reading this letter, I hope that you will not wrongly interpret the fact that I will be spending the evening with my 18 year old secretary at the Comfort Inn Hotel.  Please don't be upset - I shall be home before midnight..”  When the man came home late that night, he found the following letter on the dining room table:  'My Dear Husband,  I received your letter and thank you for your honesty about my being 54 years old.  I would like to take this opportunity to remind you that you are also 54 years old.  As you know, I am a maths teacher at our local college...  I would like to inform you that while you read this, I will be at the Marriot Hotel with Michael, one of my students.  He is young, virile, and like your secretary, is 18 years old. As a successful businessman who has an excellent knowledge of Maths, you will understand that although it may appear that we are in the same situation, there is one mathematical difference:        18 goes into 54 a lot more times than 54 goes into 18.'       Therefore, I will not be home until sometime tomorrow.......
