Mathematical Fantastical

The hypotenuse less the circumference, Makes me use words that make no sense, How I'm lost in what an expression is, Vut I know equations have an = like this.

If squaring and dividing to right or left, You find yourself feeling low or bereft, Don't worry too much rub it out restart, Maths is a computational system, an art.

There's lots of numbers and letters too, Longer it looks the more to impress you, I'm adding funny symbols for an effect, Labelling my theorems, gaining respect.

And for lucky ones with breakthroughs, Youve to recall when they make the news, They've probably spent eons on all that, Look at Einstein's hair or Schrödinger's cat.
