what is zero divided by zero?

Look here:

Gruß radix !

This is undefined.

What is the definition of undefined, thanks for the answer.

"Undefined" means there is no value for 0/0 in mathematics.  Expressions that contain or result in 0/0 are not mathematically valid.   The reason is that it can lead to illogical results (you could use it to show that 1 equals 2 for example!).

okay! but 1 can equal 2

1 banana = 2 ends

so it could be right

In that case feel free to use 0/0, but don't expect to pass too many mathematics exams!

thanks alan! have a nice day :)

with your "Banana" and "Ends" example, that's more stating:

1 x = 2 y

where x = 2y

So yes this works out fine.

However, using 0/0 you can actually 'prove' that 1 banana = 2 bananas and then draw that to an infinite scale.

1*0 = 0

2*0 = 0

1*0 = 2*0

(1*0) / 0 = (2*0) / 0

1 = 2
