What do you think 2/0 should be?

If I ask you to give the answer for 2/0, you'd probably say-INFINITY-right? Wrong. According to your answer, 2/0=infinity Now, that infinity will obviously have a numeric value,so, 2=infinityx0 Anything multiplied by 0 is 0,so, 2=0,which is not possible. Now, you might change your answer to-invalid-right? I have an answer to that too, I say, 2/0=0.2 If we convert it to percentage,then, 2/0x100=20% Then we convert it to numerical value, which is, 0.2 Do you agree?

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.

0.infinity is undeterminte form so u can't say like 0.infinity =0.

Manu Attri - 7 years ago

Thank you for comment. I am not saying that infinity=0. I am saying, infinity,to an extent,will obviously have a value. That value is thereby is being taken here.

Amisha Gupta - 7 years ago

Why have u taken 2/0=.2??

Kushagra Jaiswal - 7 years ago

Thank you for your question. 2/0=0.2 is what I am prooving.

Amisha Gupta - 7 years ago

Now I understand your point. You cancelled 0 by the 0 of 100!!! I was not able to get how u did that statement. Thats wrong u cannot do that.

Kushagra Jaiswal - 7 years ago

@Kushagra Jaiswal – Can you tell me why?

Amisha Gupta - 7 years ago

@Amisha Gupta – The cancellation of zero means both the numbers have 10 as a common factor, so we divide both numbers by 10 by cancelling the zeroes. Division by zero is not defined.

Kushagra Jaiswal - 7 years ago

@Kushagra Jaiswal – Look, its very simple you cannot a common factor of a number which is neither considered a natural number or a whole number,

Amisha Gupta - 7 years ago

We never say 2/0= infinity. We always say 2/0= not defined. Since the value cannot be defined

surbhi seth - 7 years ago

Thank you for your statement. 2/0=infinity is for those who think its correct to say like that. I am sure you are not one of them.

Amisha Gupta - 7 years ago

Dear friends, the question is do you agree with the above equation.

Amisha Gupta - 7 years ago

I would say 2/0 is not defined . And also .. infinity is not any number actually so it will never have a numeric value .

Ayush Parasar - 6 years, 11 months ago

Actually, your second line has some glitch.You are saying ∞ will have some a numeric value.∞ is not a number.It is a denotation that tells that when you will keep going you'll never reach your destination, literally. 2 divided by 0 is undefined.You can't do any mathematical operation ahead of this.
