Because there's just no sensible way to define it. For example, we could say that 1/0 = 5. But there's a rule in arithmetic that a(b/a) = b, and if 1/0 = 5, 0(1/0) = 0*5 = 0 doesn't work, so you could never use the rule. If you changed every rule to specifically say that it doesn't work for zero in the denominator, what's the point of making 1/0 = 5 in the first place? You can't use any rules on it. But maybe you're thinking of saying that 1/0 = infinity. Well then, what's "infinity"? How does it work in all the other equations? Does infinity - infinity = 0? Does 1 + infinity = infinity? If so, the associative rule doesn't work, since (a+b)+c = a+(b+c) will not always work: 1 + (infinity - infinity) = 1 + 0 = 1, but (1 + infinity) - infinity = infinity - infinity = 0. You can try to make up a good set of rules, but it always leads to nonsense, so to avoid all the trouble we just say that it doesn't make sense to divide by zero. What happens if you add apples to oranges? It just doesn't make sense, so the easiest thing is just to say that it doesn't make sense, or, as a mathematician would say, "it is undefined." Maybe that's the best way to look at it. When, in mathematics, you see a statement like "operation XYZ is undefined", you should translate it in your head to "operation XYZ doesn't make sense." /quote |

Divide by zero is not possible, but dividing by the next closest thing leads you to infinity. |

| Coolness: 43135 | the next closest thing is not zero. :)
In no serious math book will it say infinity. The correct scholar answer to the question is undefined. |

| Coolness: 339800 | if you've ever done calculus you learn about limits..
Graphing an equation where the divisor goes to 0 takes you to infinity. Granted, you cannot actually get to infinity, which is why a division by 0 is undefined, the next closest thing is infinity. |

 Coolness: 68830 | So if I'm standing besides you, the next closest thing to me, is you?
The closest thing to infinity, is finite, therefore not infinite? Infinity - 1 is not infinity But I do believe that infinity +1 is still infinity If you define infinity as the biggest thing imaginable. What is your definition of infinity? |

No, i said the closest thing to zero. Take calculus 2 and you'll understand when you learn about limits.

just to stir the shit a little more, know that there are different levels of infinity... some infinities are higher than others |

 Coolness: 55425 | I'm afriad people here are getting confused with symantics. Mathematicians frequently exchange "infinity" and "undefined". Infintiy is itself an undefined irrational number. An undefined variable is usually represented with the symbol inifinity.
But the way the original question was phrased implies that the answer should be "infinity". You can disagree with this interpretation, but you'd technically be wrong. |

| Coolness: 68830 | How would you define infinity as to have higher and lower infinities?
Obviously not the classic definition of the biggest possible thing. And a negative infinity definitely isn't the biggest thing, so how is it defined? |
