text: what is 0 divided by 0.      (0/0 = ?)?   according to most computers, it's 'nan'. which is a symbol that stands for 'not a number', or 'stop asking me silly questions'.  technically, x / y mean 'what is the number that, when you multiply it by y you get x?' so 0 / 0 means 'what is the number that, when you multiply it by 0, you get 0?'. to which the answer is obviously 'any number you like.'
