Mathematically, what is 0 (zero) divided by 0 (zero), as in 0/0?

Answer 1

Division by zero is undefined. You can't divide by zero. If you get 0/0 when trying to figure out a limit, then this is called an indeterminate form.

Answer 2

its 0

Answer 3

It is mathematically undefined.

There are several ways you could look at it that seem to give some other answer, but the rules involved always include the exception that the numbers cannot be zero.

For instance:
x/x = 1 (for all non-zero values of x)
0/x = 0 (for all non-zero values of x)
x/0 = infinity (for all non-zero values of x)

Which leaves the last - 0/0 = undefined.

Answer 4

Actually, there are about three possible answers which you could argue:

1. 0 - because 0 divided by anything is 0
2. Undefined - because anything divided by 0 is undefined
3. 1 - because a number divided by itself is 1.

As I understand it, the second option takes precedence in this case. The third option isn't really viable, as it would not make sense philosophically to start with nothing, divide it by nothing and end up with something!

Answer 5

interesting because if you put it as a fraction
5/5=1
4/4=1
3/3=1
2/2=1
1/1=1
0/0=?

just thought i'd throw that into the mixer

however
0/5=0
0/4=0
0/3=0
0/2=0
0/1=0
0/0=?

also
5/0=infinity
4/0=infinity
3/0=infinity
2/0=infinity
1/0=infinity
0/0=?

so 3 main rules
x/x=1
0/x=0
x/0=infinity

Answer 6

Although some might beleive it to be 1, the answer is actually Undefined. Any number real or imaginary divided by zero is undefined, its would be a straight vertical line on a graph and therefore hs no slope, so then the number diveded by zero doesent actually exist, its undefined

Answer 7

Dude.. 0 divided by anything is 0. I think that's covered in 3rd grade isn't it?

Answer 8

no solution, cannot divide by 0

Answer 9

A simple rule:
dividend is always = quocient x divisor + remainder.

Answer 10

0, (2 pts whoo hooo!)
