It's been a while and I was never that great at calc but for f(x)=1/x as x->-0, f(x)-> -infinity and as x->+0, f(x)-> +infinity
That describes the graph of f(x)=1/x pretty well to me.

Technically that would be the "NOT" operator rather than the negative operator.
If we use the symbol "!" to denote "NOT", like in the C language, and we define 0 as "!n" (a lack of numbers/no numbers), where n is any number, then !(!n) would revert to "n": any number.
But is "negative" actually the same as "NOT"? Well, -1 doesn't mean "not 1", it just means 1 less rather than 1 more (+1), so I'd say the proposal is invalid.Xunzian wrote:1/+0= +infinity

1/0 isn't infinity, it's undefinable.
The idea that it's infinity presumably comes from any number being divided by smaller and smaller numbers equaling higher and higher numbers that tend towards infinity.
However, consider n/n. Something divided by itself always seems to equal 1, but if n=0, then do we follow the n/0 = infinity rule or the n/n = 1 rule?

I mean, even with beavers and lions, a "not beaver" can be a lion amongst all other things that aren't beavers, but what really is a negative beaver? The same thing as a not-beaver?
You wanna define negative as a "lack of"? Sure, you can go ahead - in common parlance a "negative" can even mean a no, as in "not what you just said": basically "NOT", and a "lack of" basically means none or NOT (e.g. beavers), such as a lion.
I'm not against you playing around with definitions and seeing what happens, I'm just telling you that mathematically the problem has already been solved by distinguishing NOT and negative e.g. "-1" obviously not being the same as "!1". NOT 1 includes -1 but a whole lot more besides: namely everything else including -1, just not "1". The same can go for beavers and lions, sure...
Not sure I like the suggestion that a lion is a negative zero in your example, because so is a tree, and a lion isn't a tree. At the very least a lion is of the set NOT beaver, of which a tree et al. may also be part. Maybe that's splitting hairs, but distinguishing NOT from negative is not.

We are splitting hairs here when these two concepts converge in the special case of zero.

Well I'm honoured to have such an in-depth and mutually, life-changingly self-questioning conversation with you. Inspiring.

I gave you a perfect answer, and you gave me an insult. You know what I think about all you "doth protest too much" subjectivists??? I think you've done some horrible shit, and are trying to claw as hard as you can to avoid falling into the hell you see before your eyes ... maybe if nothing is true, you can get off on a technicality HA!!!

Division is a shorthand for subtraction. "6/3" is the number of times you can subtract 3 from 6 before you get to 0. Subtraction is a kind of addition too, just in the other direction (negative is the opposite vector direction to positive). 6/3 can also be expressed as the number of times you need to add 3 to itself (from 0) to get to 6. This is why computers only need "adders" to pull off all mathematical and logical calculations (or more precisely "half-adders", which are just AND/XOR/OR gates in a specific arrangement to channel electrical current in a certain way to make the output look appropriately and usefully different depending on what you input).
To answer 0/0, how many times do you need to subtract 0 from 0, or add 0 to 0 to get to 0? Well you're already there, but you can also do it any number of times, including an infinite number of times, meaning 0/0 is all numbers and no numbers - it's undefinable. The "n" or "p" in your example are incidental, the "/" operation is what's critical, or more precisely the "+" operation implied by"/". In this way, n/n and n/p are metaphysically the same.
"0 fitting into 1" is a kind of pie analogy that has the potential to be misleading - and you could also easily say that 0 never fits into 1. Or are you trying to imply that infinite is the same as never? That would leave you in a bit of a conundrum, if everything (infinity) was nothing (never) to you...
The clear way presents itself to those who understand where maths comes from, which I have described above. n/n when n=0 and and n/0 have no answer just the same way that paradoxes are just badly phrased questions that have no answer until you unpack them and find the internal contradiction that makes them invalid. There are many ways to categorise philosophers: an appropriate one for this situation might be to distinguish those that take on philosophy to solve internal contradictions in order to solve real problems (such as myself) from those who use philosophy as a means towards experiencing awe and mystery (such as Ecmandu and most female philosophers). The latter category gets nowhere with solving anything, instead they only further muddy and complicate things to stoke their imaginations. Whilst I support using your imagination, I do not support speculation for its own sake.Ecmandu wrote:Silluoette....

Thank you for making the effort to spell my name correctly. I know what you're saying - it's profoundly simple. It's just wrong. I have further explained the role of the "negative" sign/subtraction above - it is more of a vector direction than a NOT, as I already explained and I'm sure you understand even if you won't admit it. Negative 0 is just Positive 0 "but in the other direction" - that is to say they're the same thing.
I already sussed you out, you don't need to explain anything more to me. You want to play with definitions and see what happens. As I said, go ahead, hallucinate. Speculation can be a fun past-time and even lead back to utility in actual reality as long as you bring it back. Philosophy for the sake of philosophy has no end though, so just don't expect me to play along like a fellow child. I'll carry on trying to make reality better using truth with people who want the same instead.

Not zero, implies other numbers, in order to abstract the distinction of zero for any conversation... the not operator solves as every number but.
Opposite of does not imply this except in the case of zero... zero is the lack of all number... which means that every number except zero is being referenced when zero is its opposite, both as other numbers existing as in the first proof, and everything but a placeholder has a place (negative: the opposite of)

That's the thing though, negative isn't "opposite of", even at 0. NOT is. Negative is subtraction, which is "addition in the other direction". Does opposite direction mean complete opposite? No. It's still addition, not the opposite to addition. It's only the vector direction that changes, the vector magnitude is the same ergo: not the complete opposite.
What is the addition of 0 in the other direction? Well the magnitude of 0 is the same, so direction (the only thing that distinguishes +0 from-0) doesn't even matter at 0. You can go in any direction from 0 with 0 magnitude and you go nowhere. You remain at 0. -0 = +0 = 0.
!0 however? That's the "opposite of" and it is every number but. The NOT operator is a binary operator, so when applied to 0, it's what you're trying to say -0 is: every number (but excluding 0). As in computing, any number other than 0 is "true" and 0 is "false". True is the opposite of false, and 0 is the opposite of any other number than 0. Maths exists to straighten out the muddying that you can pull off with English, already solving problems like the one you've tried to come up with if you understand it. Yes, you can play around with definitions to see what happens, but what you want -0 to be is already accounted for by !0 so where you're trying to get to has already been gotten to - it serves no purpose.

That you don't know this explains a lot about what you're trying to do here.
2 is the addition of 2 from 0 = "0+2". 0 is that same 2 but once you "-2": the subtraction of 2 from 2, or the addition of 2 but in the opposite direction back from 2.... to 0. It's all very very simple.
What is "the distance as an opposite is 4" supposed to mean? 2-(-2) is 4, sure. How are you trying to misread me here?
Ecmandu wrote:I was a step ahead of you... 2 - (-2) is a double subtraction, which inverts what I said about subtraction itself. I'll just forget that you ev n bothered to say subtraction is addition.
