1. ## Dividing by zero

I just want to see who agrees with me. Some people i know do, some people don't. I just want to see what you think. I beleive that any number divided by 0 is infinity. Here is my reasoning:

Think about it this way, any number divided by 0 is infinity. Here is my example:

10 divided by 1 = 10
10 divided by 0.5 = 20
10 divided by 0.25 = 40

So by this reasoning, you can say that as the number you divide by gets smaller and smaller after 1, the answer gets larger and larger. If you had a number that was JUST after 0, you would have a huge number for the answer, so when you go down to zero, that number will be undefinable, therefore, infity.

2. Want to know what our 8th grade Algebra teacher says?
When you divide a number by 0, it explodes.

4. Yeah your theory makes sense, but since you cant divide anything into zero, its simply impossible....or so they say.

7. Yeah, i didnt word it well, but thats what i mean.

8. And if you divide it into a negative to you get a -invin ?

9. I don't know, i think it just goes back the other way.

10. I dont even know what a -invin is, lol.

11. argh math, It sounds right but i bet there is some advanced reasoning as to why not or it's probally somthing very simple that we are over seeing.

12. Yeah, im sure the mathmaticians know what they are talking about, but this theory isnt bad.

13. I disagree. Zero is in most respects "nothing." When dividing something that is quantifiable by "nothing," you get nothing because there are no results, the action did not take place, etc.

14. Let's look at the situations

5 divided by 0 = Error (can't divide by zero)
5 raised to 0 = 1

Zero is a number that does not make sense most of the time ;)

The reason why Zero does not work in division is simple -

12 divided by 6 = 2, than 2 times 6 = 12.
12 divided by 0 = Illegal, than that illegal number (or whatever number you think 12/0 is) time 0 = 0, it does not go back to 12 like a real division problem would.

So, in short
12/6 = 2
So, 2x6=12
12/0 = Illegal (Pick a number if you want)
So, illegal/a number x 0=0 (MUST EQUAL 12 for 0 to be divisble, but it is not, it does not go back to 12, so it can't work.)

15. But Zero isn't a number, it's nothing, so you can't divide by it.

16. It doesn't exist, so don't worry yourself about it.
Just like the decimal system really isn't the right thing to be using, i still think we should be counting in how many electrons there are on each out shell, ie 2 8 8 18 etc (although that is argueable.)

Some one does higher level math

19. This thread is quickly turning into a thread where people show off their knowledge of math. :/

Ya that makes sense. Nice thinking.

It's something to show off?
I thought it's the basics.

22. I think there is no righ or wrong answer, as even mathematicians argue other wether 0 is a number, from wikipedia:

0 as a number

0 is the integer that precedes the positive 1, and follows −1. In most (if not all) numerical systems, 0 was identified before the idea of 'negative integers' was accepted.

Zero is an integer which quantifies a count or an amount of null size; that is, if the number of your brothers is zero, that means the same thing as having no brothers, and if something has a weight of zero, it has no weight. If the difference between the number of pieces in two piles is zero, it means the two piles have an equal number of pieces. Before counting starts, the result can be assumed to be zero; that is the number of items counted before you count the first item and counting the first item brings the result to one. And if there are no items to be counted, zero remains the final result.

While mathematicians all accept zero as a number, some others would say that zero is not a number, arguing one cannot have zero of something. Others hold that if you have zero dollars in your bank account, you have a specific quantity of money in your account, namely none. It is that latter view which is accepted by mathematicians and most others.

Almost all historians omit the year zero from the proleptic Gregorian and Julian calendars, but astronomers include it in these same calendars. However, the phrase Year Zero may be used to describe any event considered so significant that it virtually starts a new time reckoning.

23. i kinda suck at math...

Don' worry, I'll counter ballence the smartness with stupidedy.

Me too, don't worry.

Try to make some damn parabolas or hiperboles or something like that.

26. Lol, all we're doing is Polynomials.

27. if 0 isnt a number, 102 = 12?

28. I dont even know what we are doing right now...I dont pay attention...

29. Originally Posted by cyanide

nope, zero by itself isnt a number

and your example would be correct if zero wasnt a digit. your getting your definitions mixed up.

and the theory is wrong, as you CAN divide by zero without the answer being infinity. You learn it in higher math.

30. How did this get into arguing about zero as a "number", the thread question can be answered without even needing to refer to zero as a number.

You can't divide one number by zero and expect it to be exactly correct. Sure there are imaginary numbers, quadratics, but this is simple
