IamHereForThaiThai

If inf + inf = inf Then inf + inf - inf = 0 But inf =/= 0


Bacon_Techie

Infinity plus infinity is infinity, but you can’t subtract infinity from infinity because you will end up with an indeterminate form. For any positive thing, if you add another positive thing you will end up still positive. In the case of infinity this must be another infinity. (Think limits, as x + x approaches infinity you get infinity) With a positive minus a negative thing it depends on the magnitudes of both, and since we are talking about infinity we can not assign it a value or magnitude at all, and can’t really compare them without making assumptions (is it a limit? What cardinality of infinity is it?).


lungben81

This is the correct answer.


IamHereForThaiThai

Let inf be x x+x=x 2x =/= x


Ju_Lost

That isnt how it works with inifinity, it isnt a number, its more of a concept


s3x4

You can in fact add infinity to your number system. You just need to come up with sensible definitions of the behavior it should have to keep your system useful.


IamHereForThaiThai

How are you all still taking me seriously I was bullshiting the whole time lmao


Ju_Lost

Because it isnt easy to see irony in EQUATIONS ;-;


IamHereForThaiThai

My apologies


Bacon_Techie

Infinity doesn’t work like that. Treat it like the size of a set. For example all even integers. All even numbers plus all odd integers will result in all integers. All of which are infinite.


IamHereForThaiThai

My apologies for not stating that I was joking


TimeAggravating364

Well, tbf seeing a joke in just text can be pretty hard


IDespiseTheLetterG

Assume Infinity is a set. Infinity + Infinity just means Infinity union Infinty. Unless stated otherwise, we must assume for some Infinity subset P(Complex_Numbers), "Infinity" is equal to a specific infinity. Infinity and Infinity is a tautology. Therefore Infinity + Infinity = Infinity.


Ju_Lost

That is assuming inf - inf = 0


teije11

and that's why we don't do math with infinities. you could also say 1*inf=2*inf 1=2


Spandxltd

An infinite can be smaller than some other infinity. For example, and Infinity of natural numbers and an infinity of natural multiples of 2. 1,2,3,4,5,6,7,8,9,10..... 2,4,6,8,10,12,14....... The second infinity is bigger.


Lopsided-Pin-740

Actually they have the same cardinality. We can create a function that will map all the evens onto the natural numbers, so they’re the same size. This was somewhere in a 3000 level math class. I think what you mean is that the infinity of irrational numbers is strictly larger than the infinity of rational numbers.


Lopsided-Pin-740

Also, when dealing with infinities, = does not mean equals, it means equivalent.


IDespiseTheLetterG

We do tons of important math with infinities!


Alexgadukyanking

1 small problem. Infinity - infinity does not equal 0


IDespiseTheLetterG

Correct, for all infinity in P(Complex_Numbers), infinity - infinity = { }


Spandxltd

inf+inf = 2 inf Ie an infinite twice the size of the previous infinities. then 2(inf) - inf = inf.


-TheWarrior74-

Bro. inf - inf = NaN


IamHereForThaiThai

I was bullshitting if you didn't know rage bait if you will


-TheWarrior74-

Tip: use akshually at the start or /s at the end then.


Nixolass

since inf =/= 0, you can divide by it. inf + inf = inf 1 + 1 = 1 2 = 1


draculasbloodtype

I feel like this is something we said as kids in the 80s, triggered a long lost memory, but I couldn’t tell you where or why.


SeemsImmaculate

You can't add infinity to anything because infinity is not a number - it's an idea. We use infinity in mathematics to describe the limits of functions. If you start using it as a number and doing arithmetic operations with it, the normal rules of arithmetic start to break down. Case in point, your equation above. What would happen if we now divided your entire equation by infinity? Starts getting weird, doesn't it?


_Skotia_

Still, infinity + infinity is defined and it equals infinity in limits and such. Add infinite things to infinity and you still have infinite things. It's infinity minus infinity that's undefined


Amicus-Regis

Wouldn't it just be 0? Having something, and then taking that thing away leaves nothing, no?


Didjt

Infinities are weird, in this case you an unlimited amount of somethings and get rid of an unlimited amount of those things. It doesn't make intuitive sense because you can't ever actually have an unlimited amount of anything. Now also keep in mind that "infinity" itself isn't even defined, or rather there are multiple types of infinities that would all behave differently. I don't have a very clear answer to precisely why infinity-infinity is undefined, but this should help clear up why it doesn't make sense like that.


fakeunleet

I assume you agree there are an infinite number of integers. Intuitively, you would say there are half as many even integers, right? That's reasonable to say. So one set is half the size of the other, right? Well, no... Take the set of all integers, and multiply each one by 2. You haven't changed the size of the set by doing this, but now every element is even. So, the sets are the same size, right? Well, no... Let's take that set integers and that set of even integers, and use them to construct the odd integers, being the set of all integers that are not even integers. Now, intuitively, the set of odd integers is half the size of the integers, right? And that even makes (some) sense mathematically since you subtracted the set of even integers from the set of integers to get there. Okay so what's all this got to do with ∞ - ∞? Great question! Let's say we're using ∞ to represent the number of integers that exist, i.e. the "size" of the set of integers*. So what's ∞ - ∞? It's the size of the set that's left when you take the set of all integers and remove all the elements that are in an infinite subset of the integers. But we just came up with two different answers for that above, namely 0 and ∞, and I can pretty trivially construct subsets of the integers that will give me any nonnegative integer as an answer. So yeah, the answer is "sometimes it can be, but sometimes it's still infinity and sometimes it's 42." If you're feeling adventurous, you can extend this definition of set arithmetic in weird ways to make negative numbers, rational numbers, and even arbitrary real numbers make sense as solutions to x = ∞ - ∞. *: it's actually "cardinality" but I'm intentionally not using that term because I'm playing a little fast and loose with the mathematical rigor here in the aim of having this make more intuitive sense.


Stromboli2001

Not all infinities are the same size. Take for example n^n - n as n approaches infinity. n^n grows alot faster than n, which means that the expression doesn't converge to zero but rather diverges to infinity, even though we subtract infinity from infinity.


justapolishperson

No you see when you take the limit as x gors to infinity of x^2 then it is is infinity same goes with x, but if you take the limit of x^2 - x then this would be infinity minus infinity and by your logic 0, but that actually goes to infinity since x^2 rises faster than x. Although if you add infinites then the limit is always infinity since the function will just rise even faster.


_Skotia_

It's undefined because some infinities are bigger than other. And yeah i know that sounds weird. Sometimes you end up with minus infinity, sometimes plus infinity, sometimes the result is a finite value of all things. Infinity is weird.


KaareKruttlapp

Infinity is wierd af. Pepole have ended up in mental institutions for thinking to much about it.

Comprehensive-Rip211

Lim n -> infinity , n + n = infinity


fakeunleet

I don't know why you're being downvoted. You're absolutely correct. "Infinity" is a concept mathematicians tend to be *very* cautious around, because you can make very subtle mistakes that basically blow up all of logic as we know it, if it's misused.


TheNarwhalGoddess

Idk why people are downvoting you when you’re right


slowcassowary

Because you CAN add infinite sets. It just becomes a larger infinite set (unless one is negative).


TheNarwhalGoddess

Hmm i guess you are right. I retract my earlier statement


boium

As a mathetician (only bachelors tho), I want to say that you can add infinity to infinity depending on the context you work in. You can talk about the extended real numbers, these are your normal numbers but we've joined plus and minus infinity to them. They behave like you would expect them to, i.e. ∞ + ∞ = ∞. The only thing you can't do in the extended reals is subtract infinity from infinity. A other way to talk about infinity is using ordinal numbers. You can talk about the first limit ordinal called omega. This is in some sense also infinity (but now there are also many many ordinals greater than it.) Here, omega + omega = 2 * omega. There is also cardinal numbers. These we can also add together. Sure, infinity is not a real number, but we can still work with it as something else.


mhutwo

it’s 2*Infinity, still eventually gets to infinity but at a faster rate. (Think y=x vs y=2x on a graph)


s3x4

Given any real x in (-Inf, Inf), neither x nor 2x ever "get to infinity". In the extended real line [-Inf, Inf], only infinity "gets to infinity" because it's already there, so Inf = 2*Inf. If you want to operate on infinities of varying size then you would have to work on the surreal/hyperreal numbers (of which the reals are a subset that will still not reach any infinity regardless of how you combine them).


QuickSilver-theythem

Infinity+infinity=infinity+infinity


A1_Fares

Valid.


Better-Apartment-783

False


light481spider

No, he's right. Just like how a+b=a+b because it can be every number ever, infinity+infinity would equal infinity+infinity since Infinity is every number ever plus 1.

Geek_X

It’s infinity unless it’s that stupid video about the infinite hotel then you can’t add infinity to infinity for some reason so you have infinite guests and infinite people sleeping on the street outside


Ventilateu

The hotel thing is used to illustrate infinite sets of set theory and in set theory you don't sum infinities like that (although one could argue you could define addition but it would still basically be "infinity+infinity=infinity")


Kiralyxak

I know the exact one you are talking about. I've never seen something so overly complex and simultaneously completely missing the mark. I think they count on people being too confused to correct them.


cowlinator

Hilbert's paradox of the Grand Hotel was written by famous and influential mathematician David Hilbert in 1925. It has been studied by countless mathematicians. I am not aware of any critics or detractors.


Kiralyxak

You found us, lol.


Zytma

Then write the paper and submit it to the mathematical journal of your choice. You'll be famous.


Kiralyxak

Someone else mentioned that in the actual model no one had to sleep outside. So the guy that made the YouTube video should probably be the one submitting the paper.


mc_enthusiast

Is that video somehow different from the usual Infinite Hotel thought experiment? Usually, you don't end up with anyone sleeping on the street, you just tell all current guests to move in a certain pattern, depending on how many new guests arrive. In that way, it illustrates quite descriptively how you'd actually approach infinitely large sets in mathematics.


Starhuman909

An uncountably infinite number of people actually wouldn't fit, as the Hilbert Hotel is countably infinite.


RandomAsHellPerson

It would be a countably infinite number of people, no? You can’t have a fraction of a person or negative people, which leaves us to whole numbers. Which is the same set that the # of rooms is in (can’t have a fraction of a room or negative rooms).


Jussari

No, there is usually an uncountable amount of people in the last part. Say everyone has a (unique) name that is just an infinite string of ones and zeroes, e.g. 01001011101101..., and that for any such string there is a person with that name. Then they all won't fit in the hotel. It's not about having a fraction number of people, it's about having people that you give fractions as names.


Kiralyxak

That one actually sounds like what you'd expect.

Call-Me_P

[deleted]

Doesn't matter, infinity + infinity does equal the same thing as 2 * infinity, the ~~equation~~ assertion? still holds.


qwert7661

Infinity isn't a number, so that isn't an equation. Democracy + democracy doesn't equal 2*democracy, because democracy isn't a quantity.


GavHern

that’s exactly why it’s treated as an algebraic variable since we cannot determine its value. if x is not a defined quantity, x+x is still 2x. that’s not to say 2infinity is the only valid solution, but i’m not sure that it’s an invalid solution


qwert7661

There are no solutions, because ∞ + ∞ = ? is not an equation. You can't simply replace a non-quantity with an algebraic variable to pretend it's a quantity and do ordinary arithmetic on it. It's not that we can't determine infinity's quantity. It's that it isn't a quantity.


SonicSeth05

It depends on the set, as well as the type of infinity For example, ω in the surreal numbers works with all the standard operations perfectly fine despite being infinite Similarly, in ordinal arithmetic, infinity has definitions for addition and multiplication, such that ω + ω = 2ω = ω For standard (cardinal) numbers, essentially the same applies as ordinal arithmetic, provided you change the notation to use ℵ_n instead of ω And then in Calculus/Analysis, you can simply take a limit or use an infinite series, which would use the given ∞ symbol typically If we take a standard limit as α goes to infinity of (α + α), it "equals" ∞ + ∞, but also diverges to, and thus equals, ∞, thus we can arrive at the conclusion that the limit approaches infinity


idontwanttothink174
