# The jpneduenumerate package for LaTeX (TeX)

## Package Information / パッケージ情報

Mathematical equation representation in Japanese education differs somewhat from the standard LaTeX writing style. This package introduces enumerative expressions in Japanese education. The termin Japanese educationhere refers to the results of my own survey of representations in authorized textbooks for high schools of several companies.

It is included in the latest version of TeX Live. You can download from CTAN4 if it is not available in \usepackage{jpneduenumerate}.

## Contents / 目次

Apology: Most parts are written in Japanese only.

## 「日本の教育における数式の表現」とは

jpneduenumerate パッケージの説明文において，私は「日本の教育における数式表現には，LaTeX の標準である書きかたとはやや異なる部分があります。」としています。

jpneduenumerate パッケージにおいては，LaTeX の標準による出力と，数社の教科書での書かれかたを比較して，次のようなものを念頭に述べています。

• 見出しの文字の使いかた
• 見出しの中における字下げ量
• 列挙前後との余白の取りかた

## The term “in Japanese education”

In the description of the jpneduenumerate package, I state that “mathematical equation representation in Japanese education differs somewhat from the standard LaTeX writing style.”

This is based on the requirement of the CTAN description (to write what you want the package to do in a concise), and was written with an eye to conveying the message to the target users, i.e., Japanese junior high and high school teachers. However, it may cause some misunderstandings among those outside of them, i.e., university educators and those who have not received mathematics education in Japanese, as to whether there is a standard for mathematical expressions in Japanese education. Therefore, I would like to explain my intention here, which is indicated in CTAN as Home Page (more information).

In the jpneduenumerate package, we compare the standard output of LaTeX with the way it is written in several textbooks, with the following in mind:

• How to use text in headings
• Amount of indentation in headings
• Margins before and after the enumeration

Samples are shown below. The width of the paper is full, and the symbols are quoted as small as possible to show their usage and margins.

The items examined are limited to textbooks that were available for viewing at my disposal. Not all textbook companies were checked.
