Is 0 divided by 0 = undefined or 0?

Answer 1

There are some real idiots on here tonight. Stone cold morons.

The correct answer is undefined.

IF x = a/b, then b times x = a, right?
So use 0 for a and b.
Use 0 for x, it works, right?
Use 1 for x, it works, right?
Use 2 for x, it works, right?
Use basically anything for x, it works, right?

So there is no defined answer other than "undefined".

Some of you ought to ashamed of yourselves. Wikipeida my butt.

Answer 2

Of course, 0/0 is undefined. One would have to have more information as to how each zero got to be zero, as, for example, a limiting process. I do not have enough space to go into sufficient details, but anyone with a rudimentary knowledge of calculus will know what I am talking about.
To Mark: You say you think you remember "learning" a rule about any number divided by itself is one. This is NOT learning, this is memorizing, which is the lowest form of intellectual activity and which we share with animals. The second level is analysis, and the third is synthesis. Some animals can go to the third level! You should NEVER accept something just because your professor said so! You have a brain, use it! Question everything!

Answer 3

It is 0.

Answer 4

As far as i know 0 divided by 0 is indeterminate.

Look at it this way, we can say that the numerator is 0.0000000000001 or is approximately equal to 0. Then 0/0 would be 0.

If we assume that the denominator is 0.0000000000001 or is approximately equal to 0. Then 0/0 would be infinite.

If we assume that both are 0.0000000000001 then 0/0 would be equal to 1.

So that is why it is indeterminate, because 0 is not an exact number. we sometimes use zero to represent a very small quantity or a negligible quantity.

Answer 5

Yes - anything divided by 0 is undefined in math.

Answer 6

It is undefined.

It may have meaning only in the limit sense if you know how the denominator and numerator behave near zero; it then may yield to any value based on its limit. But by itself 0/0 is not defined.

Answer 7

I think I remember learning that even though 0/0 is technically a division by zero, which is not pretty computationally speaking, the rule is that any number divided by itself is 1. Addendum: Some research proved the "undefined" answer more accurate than my original "1" answer. Thanks for pointing this out to me, Pavi--and, in such a polite way ;)

Answer 8

undefined

if a is not zero, 0/a=0 and a/0 = infinity
no reasonable way to combine these two into 0/0

Answer 9

0, because 0 goes into 0, zero times

Answer 10

undefined, u cant have 0 as a denominater
