Free Copy of My Book

November 1, 2011 at 9:16 am Leave a comment

A few days ago, a seventh‑grade math teacher and assistant baseball coach sent me the following request:

I would love to have a copy of Math Jokes for Mathy Folks, but I am financially unable to purchace it right now because my wife is unable to work and hasn’t been approved for disability.

Now, I like to think I’m a generous guy, but I am unable to send a free copy of my book to everyone who asks for it. A little‑known fact about the publishing industry: The majority of authors actually have to pay for copies of their own book. It’s an interesting percent problem. I pay 50% of retail price plus shipping to purchase copies of my book, but I then receive a 15% royalty on the discounted price of every copy I purchase. (You can do the math to figure out how many books I could give away for free before going bankrupt.)

So I sent the following reply:

Send me your favorite joke(s), mathy or not, and I’ll send you a copy of the book.

My correspondent responded quickly with three jokes, two of which I had never heard before. A copy of my book is in the mail to him, and his jokes are pasted below for your reading pleasure.

What’s a seventh grader’s favorite excuse for not doing homework?
I have a solar‑powered calculator, but yesterday it was cloudy.

The student’s second semester seemed so much like her first that she hoped she could graduate sooner by combining like terms.

How is an indecisive third‑base coach like multiplying or dividing by a negative integer?
In both cases, the sign changes.
