Fraction with Zero question

This is for the *genuises*. when posed with the problem, "what is the answer to 0/0?" i have come across three different solutions and im not sure which is correct:

1. since any fraction with 0 as the denominator cannot be solved, then the answer is "undefined"

2. since any fraction with 0 as the numerator is zero, then the answer is "zero"

3. finally, since any fraction in which the denominator and the numerator have the same numerical value is equal to one, the answer must be "one"


so which one is correct?

>>12

Like 9 said, but slightly differently:
DNE is shorthand for a logical statement, "the set of solutions is empty", or "the solution does not exist".
NaN and +-INF are machine specifications for values that fall outside the range of finite machine numbers. They are placeholders used so that the variable containing the solution to an equation can be specified to exist, without actually having a (finite) numerical value.
