Exploring the internet, looking for mathy poems, I came across the website Poemverse -- and I entered the search term math and was led to an exciting list of possibilities -- and plentiful outcomes also occurred when I searched using other mathy terms -- algebra, geometry, etc... I also found a collection of "Poetry for the Math Haters" -- at this link. Below I offer two verses found there -- alas, without information about the contributing poets.
Finding Humor in Math Hating
Mathematical Mischief by Jessica Rose
Oh, math, your tricks and riddles,
Leave my brain tangled and in a fiddle,
But in this battle of numbers and wit,
I'll find humor, and never submit.
Mathematical Laughter by David Scott
Math, my eternal nemesis, it seems,
Yet I'll laugh at your complex schemes,
For in this world of calculations and strife,
A little humor is the elixir of life.
AND, here is a link to some YouTube math songs!
