Nah... I cheated in my calculus exams... I had one of those Sharp
handheld computers.. which I programmed it to solve integral
calculus.... doing the assembly language was more fun than
doing the math...

Yeah but sweeping generalisations are always a great way to

Now it makes sense......
I can still markup formulas easy enough......
but I won't go any deeper... only embarass myself with my ignorance.
My only trailing comment is to say that xml markup is in itself a type
of formula language. Or, more accurately, it is a form of expression not so
much for the question, but rather the results.
