What does it actually equal? I see four possible solutions.
What would you say the answer is? |

My brain exploded while trying to understand some articles on the subject, but there is apparently an infinite amount of answers - the solution is any number except for infinity. 0 x 1 = 0 so 0/0 = 1 0 x 2 = 0 so 0/0 = 2 also etc. Dunno if that's right though!

1 apple / 1 person = 1 each 0 apples / 0 people = 0 each So 0. -=-=- ''Load, Next List!''

0 divided by 0 (or any division by 0 for that matter) has different answers depending on the situation. Take Jay's example. 0 apples into 0 people = 0 each. Makes sense. But say you look at some graphs, such as y=1/x. The asymptote, where x=0, doesn't exist - but looking at the shape of the graph, it logically stretches to infinity. So really, 0/0= whatever you want it to equal for the situation it applies to. From a programming perspective, you'd probably want a function to deal with those cases. -=-=- A mushroom a day keeps the doctor away... Keep It Simple, Shroom! |

For all intensive purposes, anything divided by 0 is undefined. I don't know if you know anything about limits, but the wikipedia explanation is pretty good about showing how the left and right limits don't equal one another, therefore no limit exists, therefore it does not approach any single answer. en.wikipedia.org/wiki/Division_by_zero Here's a couple interesting ones to get you going crazy: 0^0 = 1 0! = 1  have fun

In College we were taught that 0/0 is undefined. But using limit theory: The limit as x approaches 0 from either the left or the right, you would get either a large positive number or a large negative number, if you chose to stop somewhere in that small interval, somewhere before zero. So using 1/x and evaluating let's say, 1/(1/10,000,000,000), where x is 1/10,000,000,000, you do get an answer. -=-=- DNA |

I actually asked a calculus teacher this a few years ago. He told me that the answer actually depends on the context. Can't remember the specifics though.

Your teacher was right. Depending upon how you intend to use 1/x, the answer is either undefined, or some finite number if you use limit theory. -=-=- DNA |

I have to agree with zebeste. The simple x=x+1 in normal math terms is not possible in the sense that there is no answer. However, in programming, we use this to increment a value. So the situation would define the answer, much like the topic of what car is the best, since there are cars that are the best with miles per gallon, most capacity, tow capacity, etc. -Flame

Allo. I've been busy with school and trying to deal with reality (grandfather passed away, CISCO teachers being swapped, my shop going to...ya, let's not go there). I have been programming in SL (Second Life) working on projects for hire and selling copies of my vender system to 'large' businesses in world for some good profits (I get about $375 each time I sell a copy) as well as good remarks (apparently other venders aren't designed with good administration tools :shrugs .Other than that, I've been also busy learning new programming languages (C#, Java, C++, PHP, LSL) and trying to keep up with my studies. Sorry for the off topic post. ^^; -Flame

Flame!! Welcome back!! woot! Back on topic, there's always the obvious point that 0 doesn't actually physically exist.. Anything greater than one is a physical number, since you can have 1 apple.. 0 is not actually a number.. it's the idea of nothing, that was inevitably given a value so that it could exist. . But it still doesn't! It's still just a concept. -=-=- ''Load, Next List!''

Well, I think 0 exists just as much as -1 does, or i does, for that matter. I think to say that 0 does not exist is a fallacy; if there are 0 of something, then it does not exist, however 0 itself does exist. I see numbers as being a concept, regardless; they have applications, but when working just with numbers they are their own field. |edit| Welcome back flame! |edit| -=-=- YouTube Twitter Computer Science Series: Logic (pt1) (part 2) (part 3) 2's Complement Mathematics: Basic Differential Calculus
