You're dividing nothing by nothing so logically it should equal nothing.

If I have no friends and don't have a pie to divide amongst them then nobody gets no pie.

>> No.10559663

There is no meaningful way to interpret division by 0 so logically your expression shouldn't mean anything. Which it doesn't.

>> No.10559678

In short - any answer counts as correct, not only 0, so there is no meaning in this equation.

Study set theory and linear algebra. Deal with empty set and for example the span of the empty set. Does that gives you and idea of nothing? Empty?

But when thinking about number zero.
One can say, well is just number, just a position in the number line. But not any position, is very special because is the additive identity. You can think: "to add nothing". But this 'nothing' really has to have anything to do with your intuitive idea of nothing?

Not really. The limit indicates 1. It isn't the same thing.

>> No.10565462

This isn't what you asked for but I'm sure it will help

0/0 is simply undefined space. That means that if you can act on it, then it is not in the means and Richard Feymann wasn't actually a good teacher, just a good soldier to Nixon and them. But then that also means that this is derived from another function and it can into induction. With that in place, there isn't a way to calculate for a mean that there is a dispute in its person for it to use more than its person as the dispute, that means that this is a guessing game for him to stand on and for you to elimiate yourself from your own products of faculty, into the schools, so that they may own them even if you fail, pass or just use the mind instead of the work to calculate into the means. If that arrives at conjecture, the person that isn't capably away may say that it is undefined and be correct but the person that says it is X is more wrong than that. That means that unless you actually arrive at a means for it all to unrave into a 0, there is a use for the function to equate a nature of sucrose away from the ions, and use the proton nature in it, as Physics for Feymann criteria, the person that does not dispute for it in mass is the person that has laid it in to the plans for a table that will suggest an evil can digress into mathematics and there will be a use of it into the churches. Or they will be burning them down to the ground to prove the point that they can do both and that's still evil. It isn't difficult to just recall that there may be a value in 0/0 and reach to it with all other values that reach to it for as a 0 in numerator or denominator to simply create to yourself the digest of a popular number in series, like in physics for out of mathematics, so that you can engage in conversation and not discussion. Unless you are the evil person. That makes it a moot category and all that will prevail into this, they may make a category for zero into the null types.

Analogy for fruit dividing works only for natural numbers. If my metronome clicks 1 time per second what’s the period of oscillation? 1 second. If my metronome clicks zero times per second what’s the period of oscillation? Well it’s bigger than any number, roughly speaking - infinity.

x = 0/0
0*x = 0
x could be literally any number and the expression is valid

Ergo x is not defined. It's like writing down the words "a number" and trying to prove your statement refers to 5. A well-defined operation points to one unambiguous answer, that's why the square root is defined as the positive root.

>> No.10565653

I don't see the difference. But I am a dummy. If you're not busy I'll read a reply tomorrow. Sounds like you are talking about a metronome that's not moving? Or going slowly? Zero per second can still be a click a week. It's lack of movement is infinite movement? Does Zino paradox have anything to do with this?

>> No.10565698

From the ratio 0:0 we can gleam nothing about the relative size of each part,
Just like how (infinity):(infinity) equals 2(infinity):(infinity) equals 3(infinity):(infinity), etc, so too does 0:0 equal 3*0:0, equals 4*0:0, equals 5*0:0, etc. Just as infinity has additive absorption, 0 has multiplicative absorption, and thus operations derived from multiplication, such as division, will yield us no useful information from which we can determine anything. They are—in a word—indeterminate.

You can’t properly define 0/0. If 0/0=1 then all limits 0/0 and inf/inf are also 1. For example Lim(x->inf) x/exp(x) = 1, that is not correct.

>> No.10566007

The division is not really happening.
By taking a number and dividing by zero you're taking a tangible something and splitting into nothing, which cannot happen because you always have at least what you started with, or an infinitesimally small portion of it, wherever else in between.
Even if we make it 0/0 to try and get around this logical issue, we have nothing and split it into nothing. Did a split really occur? How can you manipulate nothing? A problem with this is that generally n/n = 1 but 0/0 =/= 1
Exactly right, the division doesn't happen

Why shouldn't x/0 simply return the set of all numbers then? We could say division by zero adds dimensionality, you move from working with individual points on a number line to working with all the points. Then when you need to work backwards, and ask the question of what is the set times 0, you get 0 because 0 sets is 0.
0/0 would also be a special case that returns 0 because the set of all 0s is 0.

>> No.10566521

One of the reasons is that it results in conflicting logic. Any number divided by itself gives you an entire unit of the totality of that number, aka 1. At the same time, no matter how many zeros you add up, you will never reach 1.

In other words, if you divide nothingness with nobody, then everyone (noone) will get the entirety of nothing (its unit), which is nothing.

Either we conclude that 1 = 0 and basically fuck ourselves in the ass or we decide that this can't be possible.

>> No.10567520

OP modern mathematics just just masturbatory nonsense.
It's all self referential and uses it's own rules to "prove" it makes sense.

That why it's obvious anything divided by zero is zero in real life, but in mathland is means everyone gets infinite amounts of some of the nonexistent pie.

>> No.10568104


>> No.10568182

Because division isn't actually a thing, its shorthand for multiplying by a multiplicative inverse. We justify the inclusion of multiplicative inverse so that we dont have to say each time that we're multiplying by some number such that, when you multiply by x, you return back to the original number. Instead we just say "divide by x". Because we know that generally x is going to have some inverse y satisfying xy=1. Then by commutative and associative property we can really figure out what it means to "divide".

0 divided by 0 could only be interpreted as a number such that when you multiply by 0, you get 0. But that's every number. So there isn't a unique answer. More generally, there is no number satisfying 0x=1 so "dividing" by 0 can not happen, because 0 doesn't have an inverse.

So what you're saying is each no one receives one none. Therefore 0/0=1 just as X/X=1.

Exactly right, its not a number, but its wrong to still return nothing. The answer is the set of all numbers. Dividing by zero should induce a switch to set logic.

>> No.10569252

It is defined by the fact, that you divided nothing into not a piece therefore you do not have a piece. Real question is if "not a piece(piecen't)" is a piece in context of "not having a piece"

Math is inherently flawed and the inability to define what 0/0 is is the core of the problem.
Everything else is built on top of the idea that we should just push it under the rug and pretend it didn't happen. Everything built on a fundamentally flawed set of rules is automatically flawed as well

>> No.10569498

Technically 0 can be the hypotenuse for a triangle with side lengths 1 and i. Your mistake with this image is drawing side length for i, though. It's imaginary, so hypotenuse length 0 makes sense.

>> No.10569560

That's nonsense logic, 0^0 is undefined. You're trying to say that if we could apply the same logic with 0 as other numbers, then it will equal 1. But you're using circular logic.

Well, world relies on circular logic.
