Here is something that piqued my interest.

Just read the superscript one as being directly above the subscript square-root three, marking the range of the integral, and the superscript three near the end as making the root after it a cube root. Note: the _ represents a superscript.

∫ 1√3 z2dz • cos 3π/9 = ln 3√e

The reason I like this equation is that it can be read as a limerick.  No, seriously.  I’ll set it off a bit for those that might like to try to work it out themselves…

 

Integral z-squared dz

From one to the square root of three

Times the cosine

Of three pi over nine

Equals log of the cube root of e.

It's even true!

Here is another math limerick, expressed by an equation:

 

A dozen, a gross, and a score
 Plus three times the square root of four
     Divided by seven
     Plus five times eleven
 Equals nine squared plus zero, no more!

There was a young pilot named Bud,

who didn't check things like you should.

In being too keen,

he forgot the three green,

and buried his props in the mud.

 

 

Haha, these are good! Here's a more readable form of the first one (using http://quicklatex.com/):

Thanks, Barry. I've replaced #2's equation with a quicklatex version.

While there are a lot of mathematical limericks, few of them are given in the form of an equation, which is why I find them so challenging to solve.

Thanks for the additional limerick, Alan!

I'm too dumb to question smart people!
