\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.}

\maketitle
The Institute of Reproducing Kernels is dealing with the theory of division by zero calculus and declares that the division by zero was discovered as $0/0=1/0=z/0=0$ in a natural sense on 2014.2.2. The result shows a new basic idea on the universe and space based on the new concept of division by zero calculus: for the function $f(z) = 1/z$
$$
f(0) = 0
$$
since Aristotelēs (BC384 - BC322) and Euclid (BC 3 Century - ), and the division by zero is since Brahmagupta (598 - 668 ?).
In particular, Brahmagupta defined as $0/0=0$ in Brāhmasphuṭasiddhānta (628), however, our world history stated that his definition $0/0=0$ is wrong over 1300 years, but, we showed that his definition is suitable.

we presented the basic results on October 23 and

and the abstract: 201810.23abstract.
\bigskip
Particularly, note that the division by zero calculus is a fundamental definition based on the basic assumption that may be considered as a new axiom for its importance.
As stated
by some physicist
\medskip
{\it Here is how I see the problem with prohibition on division by zero,
which is the biggest scandal in modern mathematics as you rightly pointed
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.

We have the formula
$$
\frac{a^2 + b^2 - c^2}{a^2 - b^2 + c^2} = \frac{\tan B}{\tan C}.

If $ a^2 + b^2 - c^2 =0$, then $C = \pi/2$. Then,
$$
