Zero Divided By Zero: Is There More To It?
Is this only an insolvable question or can it also lead to some useful conclusions?

“Imagine that you have zero cookies”, Siri’s response begins, “and you split them evenly among zero friends. How many cookies does each person get? See? It doesn’t make sense. And Cookie Monster is sad that there are no cookies, and you are sad that you have no friends.” This is the comical answer that Apple’s vocal interface, Siri, responds with when asked what zero divided by zero means. The answer seems absolute and one may think that Siri is questioning the sanity of a person asking such a question.
THE QUESTION OF DIVIDING ANYTHING BY ZERO BECOMES MORE OF A PHILOSOPHICAL QUESTION THAN A MATHEMATICAL ONE.
But really, is that all there is to the problem of zero divided by zero? In mathematics, anything divided by zero is undefined. For example, when we take zero and divide it by any number, the answer can never take us back to the original equation. Division is the inverse of multiplication, and in principle we should be able to trace the original equation back from the answer. But that is impossible when a zero is involved; it seems as if all of mathematics breaks down when we approach this mysterious number. Thus, the question of dividing anything by zero becomes more of a philosophical question than a mathematical one. The number is much like a black hole, where everything seems to stop and anything that interacts with it can never be restored to its original state.
Consider the problem of multiplying anything by zero. Subatomic particles such as photons and bosons have a zero rest mass. By that logic, the momentum of these subatomic particles would also be equal to zero, which we know isn’t true for all cases. So the logical problem of 0/0, or anything divided or multiplied by zero, which can be equally argued to equal zero as well as one, depending on a person’s perspective, has real world applications. How can it be equal to one, you may ask? If we divide 0.01 by 0.01, we will get 1 as the answer. Similarly, if we take the equation 0.0000001/0.0000001, the answer will still be one. So as we approach zero by increasing the number of decimal places, one may argue that an approximation of 0/0 will also be equal to 1, since 0.00000001/0.00000001 is equal to 1. Mind boggling! Isn’t it? This is another example of why zero divided by zero can be looked at in such different ways.
However, one may be surprised to learn that in calculus, zero divided by zero has a lot more significance and applications than people realize. Consider a curved graph on the XY axis. One may draw a tangent at a point and find its slope or gradient at that point. Simple enough!
But what about curves with slight curvatures, where it might be difficult to figure out where the tangent may be drawn? How can we find the derivative there?
Where the tangent is unclear, we can figure out the slopes of two cutting lines. The height and width between the two lines will give us the gradient. But as we decrease the height and width of the triangle, the gradient will approach accuracy. Hence, the zero as height and zero as width will help us find the tangent. One may ask here, how?
Consider the graph of the function of x2. If we suppose that the limits are ½ and ½ + W, where ‘W’ is the width of the triangle and consequently the number of units covered on the x-axis by the tangent, we will be able to come up with an expression for the height of the triangle. As we plug in ½ and (½ +W) into the equation y=x2 and find the difference between the two expressions, we obtain the height as the expression 2(½ )W +W2 after expansion.
So when we find out the gradient of this point on the curve, we are left with the expression ‘2(½ )+ W’ when we divide ‘2(½ )W+W2’(height) by ‘W’ (width). Here is where the assumption of zero divided by zero comes handy; as we’ve supposed that the smallest value we are taking for width in order for the derivative (tangent) to be as accurate as possible is zero, we are left with 2(½ ) which is basically 1 after we substitute W=0.
Why is this so important? This is the proof for the differential formula. Something we commonly see as:
You can test this out yourself. The differential of x2 is 2x by the differential formula. At the point x=1/2, the derivative (or tangent) is equal to one. Viola!
Thus it can be said that, in a way, zeros have helped us find the roots of calculus. Where they seem to break all rules of algebra, they form the fundamentals of another branch of mathematics. And that is the beauty of this subject. The infinities and uncertainties are just as important as anything else!

out} (2017.10.14.08:55),
\medskip
\noindent
it seems that the long history of the division by zero is our shame and our mathematics in the elementary level has basic missings. Meanwhile, we have still great confusions and wrong ideas on the division by zero. Therefore, we would like to ask for the good corrections for the wrong ideas and some official approval for our division by zero as our basic duties.

\title{\bf Announcement 461: An essence of division by zero and a new axiom}
\author{{\it Institute of Reproducing Kernels}\\
kbdmm360@yahoo.co.jp
}
\date{2018.11.10}
\maketitle
In order to see an essence of our division by zero calculus, we will state a simple survey.
As the number system, division by zero is realized as the {\bf Yamada field} with the definition of the general fractions $a/b$ containing the case $b=0$, and its various meanings and applications are given. In particular, see \cite{msy} and see also the references.
The field structure is, of course, fundamental in the algebraic structure.
However, apart from various motivations and any background, we will give the definition of the division by zero calculus as follows:
\medskip
For any \index{Laurent expansion}Laurent expansion around $z=a$,
\begin{equation} \label{dvc5.1}
f(z) = \sum_{n=-\infty}^{-1} C_n (z - a)^n + C_0 + \sum_{n=1}^{\infty} C_n (z - a)^n
\end{equation}
we define the division by zero calculus
\begin{equation}\label{dvc5.2}
f(a) = C_0.
\end{equation}
For the correspondence \eqref{dvc5.2} for the function $f(z)$, we will call it {\bf the division by zero calculus}. By considering derivatives in \eqref{dvc5.1}, we {\bf define} any order derivatives of the function $f$ at the singular point $a$ as
$$
f^{(n)}(a) = n! C_n.
$$
\medskip
The division by zero calculus seems to be strange firstly, however, by its various applications and results, we will see that the concept is fundamental in our elementary mathematics, globally. See the references.
For its importance, the division by zero calculus may be looked as a {\bf new axiom.}
\medskip
Firstly, for the fundamental function $W= F(z) = 1/z$, we have, surprisingly
$$
F(0) = 0.
$$
We see its great impacts to our basic idea for the space and in our Euclidean space.
From the form, we should consider that
\begin{equation}
\frac{1}{0} =0.
\end{equation}
Note that this representation and identity is not any result, but it is only the definition of
$\frac{1}{0}$. Of course, it is not the usual definition as the solution of the equation $0 \cdot z =1$. Here, we are stating that the division by zero calculus and the form of the elementary function lead us to the identity (0.3).
\medskip
\bigskip
{\bf \Large Could we divide the numbers and functions by zero?}
\medskip
For this old and general question, we will give a simple answer.
For any analytic function
$f(z)$ around the origin $z=0$ that is permitted to have any singularity at $z=0$ (of course, any constant function is permitted),
we can consider the value, by the division by zero calculus
\begin{equation}
\frac{f(z)}{z^n}
\end{equation}
at the point $z=0$, for any positive integer $n$. This will mean that from the form
we can consider it as follows:
\begin{equation}
\frac{f(z)}{z^n}\mid_{x=0}.
\end{equation}
\bigskip
For example,
$$
\frac{e^{x}}{x^n}\mid_{x=0} = \frac{1}{n!}.
$$
\medskip
{\bf \Huge In this sense, we can divide the numbers and analytic functions by zero.}

ゼロ除算、ゼロで割る問題、分からない、正しいのかなど、 良く理解できない人が 未だに 多いようです。そこで、簡潔な一般的な 解説を思い付きました。 もちろん、学会などでも述べていますが、 予断で 良く聞けないようです。まず、分数、a/b は a 割る b のことで、これは 方程式 b x=a の解のことです。ところが、 b がゼロならば、 どんな xでも 0 x =0 ですから、a がゼロでなければ、解は存在せず、 従って 100/0 など、ゼロ除算は考えられない、できないとなってしまいます。 普通の意味では ゼロ除算は 不可能であるという、世界の常識、定説です。できない、不可能であると言われれば、いろいろ考えたくなるのが、人間らしい創造の精神です。 基本方程式 b x=a が b がゼロならば解けない、解が存在しないので、困るのですが、このようなとき、従来の結果が成り立つような意味で、解が考えられないかと、数学者は良く考えて来ました。 何と、 そのような方程式は 何時でも唯一つに 一般化された意味で解をもつと考える 方法があります。 Moore-Penrose 一般化逆の考え方です。 どんな行列の 逆行列を唯一つに定める 一般的な 素晴らしい、自然な考えです。その考えだと、 b がゼロの時、解はゼロが出るので、 a/0=0 と定義するのは 当然です。 すなわち、この意味で 方程式の解を考えて 分数を考えれば、ゼロ除算は ゼロとして定まる ということです。ただ一つに定まるのですから、 この考えは 自然で、その意味を知りたいと 考えるのは、当然ではないでしょうか？初等数学全般に影響を与える ユークリッド以来の新世界が 現れてきます。
ゼロ除算の誤解は深刻：
最近、3つの事が在りました。
私の簡単な講演、相当な数学者が信じられないような誤解をして、全然理解できなく、目が回っているいるような印象を受けたこと、
相当ゼロ除算の研究をされている方が、基本を誤解されていたこと、1/0 の定義を誤解されていた。
相当な才能の持ち主が、連続性や順序に拘って、４年以上もゼロ除算の研究を避けていたこと。
これらのことは、人間如何に予断と偏見にハマった存在であるかを教えている。
まずは ゼロ除算は不可能であるの 思いが強すぎで、初めからダメ、考えない、無視の気持ちが、強い。 ゼロ除算を従来の 掛け算の逆と考えると、不可能であるが 証明されてしまうので、割り算の意味を拡張しないと、考えられない。それで、 1/0,0/0,z/0 などの意味を発見する必要がある。 それらの意味は、普通の意味ではないことの 初めの考えを飛ばして ダメ、ダメの感情が 突っ走ている。 非ユークリッド幾何学の出現や天動説が地動説に変わった世界史の事件のような 形相と言える。

ゼロ除算の４つの誤解：
ゼロ除算の４つの誤解：
１． ゼロでは割れない、ゼロ除算は 不可能である との考え方に拘って、思考停止している。 普通、不可能であるは、考え方や意味を拡張して 可能にできないかと考えるのが 数学の伝統であるが、それができない。
２． 可能にする考え方が 紹介されても ゼロ除算の意味を誤解して、繰り返し間違えている。可能にする理論を 素直に理解しない、 強い従来の考えに縛られている。拘っている。
３． ゼロ除算を関数に適用すると 強力な不連続性を示すが、連続性のアリストテレス以来の 連続性の考えに囚われていて 強力な不連続性を受け入れられない。数学では、不連続性の概念を明確に持っているのに、不連続性の凄い現象に、ゼロ除算の場合には 理解できない。
４． 深刻な誤解は、ゼロ除算は本質的に定義であり、仮定に基づいているので 疑いの気持ちがぬぐえず、ダメ、怪しいと誤解している。数学が公理系に基づいた理論体系のように、ゼロ除算は 新しい仮定に基づいていること。 定義に基づいていることの認識が良く理解できず、誤解している。
George Gamow (1904-1968) Russian-born American nuclear physicist and cosmologist remarked that "it is well known to students of high school algebra" that division by zero is not valid; and Einstein admitted it as {\bf the biggest blunder of his life} [1]：1.
