Well a rule can come as:
sin(x)/x = "/" / \ "sin" x / x
Or as follows:
if(x<2,x,x) = "if" /  \ "<" "" x / \  x 2 x
ifthenelse is also a rule, like any other operation.

The moment you introduce monkey business to help you teach your shit of limits, differentiability and the ubiquitous crap such as abs(x) not being differentiable at x=0, then you are no longer dealing with calculus, but something else ... shit.
