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

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

Otherwise, \( \infty = \infty + 1 \implies 1 = 0 \), which is obviously not true. Siddhartha Srivastava · 2 years, 1 month ago

Infinity is a concept not a number. Thus it cannot be treated as a number. And also two infinitys are never equal. Sid 2108 · 2 years, 1 month ago

@Sid 2108 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. Miloš Novotný · 1 year, 12 months ago

@Sid 2108 I perfectly agree with you. There may be infinite types of infinities Shreyas Garkhedkar · 2 years, 1 month ago

@Sid 2108 You are absolutely true . There are many types of infinities like in various sequences. Sriram Venkatesan · 2 years, 1 month ago

infinity is concept of numbers but it can't be defined so it's not true Krishna Bansal · 2 years, 1 month ago

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?? Kamala Ramakrishnan · 1 year, 11 months ago

Infinity is used to indicate very large number which we can't even imagine. It is a theoretical concept. Aman Kumar · 1 year, 11 months ago

Here lies the fallacy... infinity is a relative concept...its not an absolute number...hence it fails to satisfy laws of algebra... Rahul Singh · 2 years ago

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

infinity is something , which is taken sometimes for FOR DOES NOT EXIST condition or sometimes when we take a very large no. Shounak Paul · 2 years, 1 month ago

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.

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. Shriram Lokhande · 2 years, 1 month ago

If you do what is in the brackets first you get ∞^2... which is still ∞ Eric Hammer · 2 years ago

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. Rishabh Chandra · 2 years, 1 month ago
