Show Your Work by Shane D. Williams
 
I counted to eleventeen,
divided that by why,
multiplied by forty twelve,
and had a piece of Pi.
 
I climbed up a geometree,
applied a cute subfraction,
minimized a polly-gone
with angular protraction.
 
I calculated clockwise
in an algorythmic section.
Denominated digits with
mathematical perfection.
 
I summed up some sum differences,
Then solved the quadric core…
And that is how I figured out
that two plus two is four.
