Come up with some fun "equation Limericks"

WARNING: What you see below is my first-ever attempt at poetry in English.

My take on the classics: $e^{\pi \cdot 2i} = 1$.

We start with the constant called $\pi$ / And then multiply by $2i$ / Apply exponential / (This step is essential) / And one's the result who-knows-why!

Take two thousand one ninety seven,

Find cuberoot and add to eleven.

Now divide this by eight,

And get almost by fate

The number of vowels in "heaven".

[equation $(\sqrt[3]{2197}+11)/8=3.$]
