0 division help

Let x be any real no.

Then, if we do as follows:

0x\frac { 0 }{ x } , we get 0 as only x×0x\times 0 is 0

If we do x0\frac { x }{ 0 } it is indeterminate or not defined.(I know the reason)

But if we do 00\frac { 0 }{ 0 } we say the answer is 0. Is it really 0 or indeterminate because 0* any no. is 0 so should'nt the answer be not defined.

Please help.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Any number divided by 00 is undefined.

Dividing by a certain number is the same as multiplying by its multiplicative inverse.

The multiplicative inverse of 00 is not defined. You can try to define it, but you're going to run into inconsistencies. You can try to patch those inconsistencies by giving 010^{-1} more properties. Then you're going to run into other inconsistencies. Finally you may be able to do it, but it won't be of much use.

Some things are best left undefined.

So you mean 0/0 is undefined. Right?

@Satyajit Ghosh Who says 0/0 is 0. That person is mad. Of course it is undefined

It means that you cannot determine the answer.

As x * any no. cannot give x

Hmm the answer should be not defined because 0/0 can also be equal to 1 like 2/2,3/3 are equal to 1 and it can also be 0 because 0 has no value ,so the answer can't be defined ^_^
