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

Top NewestThe 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.

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

\(\infty\) ^2 is not \(\infty\)
Log in to reply
It is

OK I didn't know.

infinity -infinity is not 0
Log in to reply
infinity is concept of numbers but it can't be defined so it's not true

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??
Log in to reply
Infinity is used to indicate very large number which we can't even imagine. It is a theoretical concept.
Log in to reply
Here lies the fallacy... infinity is a relative concept...its not an absolute number...hence it fails to satisfy laws of algebra...
Log in to reply
your 2 infinites are not equal in the second line {unless infintiy is 4, which clearly it isnt as it isnt a fixed number}
Log in to reply
infinity is something , which is taken sometimes for FOR DOES NOT EXIST condition or sometimes when we take a very large no.
Log in to reply
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!

You have done wrong calculation.

I don't exactly know how Infinity works but my teacher once told me that infinity minus infinity is not 0
Log in to reply
No

Here two things are wrong ..
2 . \(\infty - \infty\) is not defined , it is an indeterminate form.
Log in to reply
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.

infinity - infinity is not 0

Check into the Hilbert Hotel.
Log in to reply
Infinity isn't a number,its a thing you may say,so you can't treat it as a number
Log in to reply
It is not true. I don't understand what is it .
Log in to reply
\(\infty - \infty \neq 0 \)
so you can't do like that !!!
Log in to reply
If you do what is in the brackets first you get ∞^2... which is still ∞
Log in to reply
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.
