Could it be Possible ? Maybe Confusion

I was scribbling in my note yesterday, when I thought to write something about infinity algebraic expressions. After many tried sums, I had found out a very strange expression in my note.

As I tried to solve it, I saw something very keen and interesting which is in the image.

Is it true ? I too don't think so, but think maybe could be true Like if agree. . Share if you find confusing and interesting or disagree

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.

Thanks for getting me right !

I agree with the others - infinity is a concept, not a number.

But aren't you contradicting your own statement? If [(infinity)^2 = infinity] and [-2infinity2 = infinity], then isn't infinity-2 = infinity??

Infinity is used to indicate very large number which we can't even imagine. It is a theoretical concept.

0\infty - \infty \neq 0

so you can't do like that !!!

If you do what is in the brackets first you get ∞^2... which is still ∞

Here lies the fallacy... infinity is a relative concept...its not an absolute number...hence it fails to satisfy laws of algebra...

your 2 infinites are not equal in the second line {unless infintiy is 4, which clearly it isnt as it isnt a fixed number}

infinity is something , which is taken sometimes for FOR DOES NOT EXIST condition or sometimes when we take a very large no.

This reminds me of myself back then. No, infinity is an idea/concept. There's no way you can treat it as a number, thus you can't solve it.

Cheers!

infinity is concept of numbers but it can't be defined so it's not true

I don't exactly know how Infinity works but my teacher once told me that infinity minus infinity is not 0

Lets consider infinite as n for simpler conventions to facilitate operations ...so n is large no. n^2 is of even larger order we cannot add them both as they are of diff orders /or subtract them.

Here two things are wrong ..

  1. The laws of algebra hold on real number system , \infty and - \infty don't belong to real number system , they can be thought as an extension to real number system.

2 . \infty - \infty is not defined , it is an indeterminate form.

It's = Infinity Because Infinity is a concept not a number. Thus it cannot be treated as a number. And also two infinitys are never equal.

If you go by the standard Set Theory, there are like 5 useful types of infinities. For example set of natural numbers is of the same size as the set of all primes.

I perfectly agree with you. There may be infinite types of infinities

shreyas garkhedkar - 4 years, 9 months ago

You are absolutely true . There are many types of infinities like in various sequences.

The fallacy is that \infty is not a number and does not follow the laws of algebra.

Otherwise, =+1    1=0 \infty = \infty + 1 \implies 1 = 0 , which is obviously not true.
