I stumbled upon an interesting thread on another forum (alas I cannot remember where it was) in which the matter of X/0 was debated quite extensively, and if I can recall it was determined that it isn't truly indeterminate, but rather stated to be so because the answer is equally as useless (infinity or something relating to it. My memory is a bit sketchy on the matter.) Of course I am certain that no-one in that particular thread were career mathematicians, but it was an interesting conversation none-the-less.

Unfortunately I cannot go into great detail on the greatest annoyances in my life, as they fall into the all encompassing scope of religion and faith, and thus cannot be discussed on this particular board. So suffice it to say that the greatest annoyance to me is the idea that can avoid all attempts to snuff it out through evidence to the contrary, and yet manages to squirm away by modifying itself, and then whose supporters have the audacity to discredit an idea that has evidence in support of it by discredited that evidence as "insufficient" or inconclusive". And no I am not talking about religion, just an idea that stems as a result of it.
