Gosh, that sounds a lot like an axiom, Troll Boy. (Hee, hee!)
In a vain attempt to rescue his Wacky New Calclueless work, Troll Boy has banned empty sets, infinite sets, axioms, rules of logic, repeating decimals, pi, root 2, negative numbers and zero. He has declared as undefined derivatives of linear functions and derivatives at points of inflection and who knows where else.
Finally, Troll Boy has now actually ALLOWED something in his goofy "system:" We are allowed to do division by zero! (An axiom?) His goofy system actually requires it. Once again, we see what a dead end and a complete wasted of time it is.
