### XXXIII for Increased SEO

.

 Beware the Ides of October! Check back on October 15 for a MJ4MF World Premiere!

Today is 10/10/13, or X/X/XIII in Roman numerals. Three years ago, I published XXX Rated to celebrate 10/10/10, and it has consistently been one of my most visited pages. Not surprising. Today’s top searches which led to my blog were:

• xxx sex
• sex xxx
• metric system jokes
• xxx.sex

Well, at least someone was looking for math jokes when they found my blog!

In honor of National Metric Day* and to appease most people who stumble across this blog, here’s a joke that mixes metric and sex. It’s subtle; pay attention.

The metric conversion for 69 is 181.

And another?

What do sex and metric conversions have in common?
I enjoy doing both, but most of the time I do them alone in my room.

And a sorta, kinda Roman math joke…

A Roman soldier walks into a bar. “Martinus, please.”

The bartender replies, “You mean martini?”

The soldier says, “If I wanted more than one, I would have asked for it!”

And finally…

When is 6 equal to 8.5?

In Roman numerals, the number SIX can be translated to 8.5. Remember that IV = 4, because a smaller number (I = 1) precedes a larger number (V = 5). With SIX, S = ½, I = 1, and X = 10. Since both S and I precede X, they should be subtracted: 10 – ½ – 1 = 8.5. Hence, 6 = 8.5. Q.E.D.

* Not an official holiday. See Pat Naughtin’s declaration as well as the U.S. Metric Association Metric Week.

### XXX Rated

Today is 10/10/10, which Julius Caesar and others might have written as X/X/X. In honor of the date, today’s post contains some XXX‑rated jokes. (Okay, not really. There is no pornography. But today’s jokes are slightly off‑color and probably not appropriate for the classroom. Then again, I know a high school teacher who used the following mnemonic to help students remember SOHCAHTOA: Sex Over Hot Coals Adds Heat To Ordinary Affection. So perhaps I don’t really know what is and isn’t classroom inappropriate.)

But before we get to the jokes, a math problem for you containing three 10’s. When the following expression is written in standard form, how many digits does it contain?

101010

(By the way, for all you code geeks, that expression was done with straight HTML. No MathML required! It simply uses nested <sup> tags.)

Okay, to the jokes…

How is sex like a fraction? It’s improper when the larger one is on top.

What is the square root of 69? Eight something.

What is 6.9? A good time interrupted by a period.

I was hanging out in an Internet cafe when my server went down on me.

Calculus teachers do it to the limit.
Statisticians probably do it.
Combinatorialists do it discretely.
Algebraists do it in groups.

No post about dirty math jokes would be complete without…

Speaking of integrals, here’s a half-assed integral:

And a slightly longer one…

The math professor explained to her students that there would be no acceptable excuse for missing the final exam. “Unless you or a loved one dies, I expect you to be here,” she told them. “No other excuse will suffice.”

“Sorry, Johnny,” the professor said. “You’ll just have to write with your other hand.”

Finally, I’ll leave you with my favorite dirty math problem, which I love mainly because of its subtlety:

A mother is 21 years older than her son. In 6 years, she will be 5 times as old as her son. Where is the father?

The Math Jokes 4 Mathy Folks blog is an online extension to the book Math Jokes 4 Mathy Folks. The blog contains jokes submitted by readers, new jokes discovered by the author, details about speaking appearances and workshops, and other random bits of information that might be interesting to the strange folks who like math jokes.
