The Dreaded Trapezium
The Dreaded Trapezium clouds the mathematical waters wherever he goes! This vicious little quadrilateral wreaks havoc on even the most tightly woven equations, formulae, and homework assignments throughout the seven seas.
Understood by only a few well-schooled geometrical experts, he seems able to turn a new side toward any creature he encounters. The Trapezium doesn't seem to fit neatly into any known matrix of scientific classification. And, the full extent of the habitat of this ocean denizen is unknown, for it is quite difficult to calculate its range in square miles.
Don't let the apparent simplicity of this problematic piscine predator (or any of the other bizarros at rickzworld) fool you! The neophyte algebra angler and the professional prime-function fisherman both know: when you've got a Trapezium on your line, you've got trouble!
Luckily for most of us, these tough little creatures tend to occupy only very deep waters. So, as the oldtimers say, "Stay shallow — and stay safe!".
