# align環境を使って複数行の数式を書く方法

これは、～による21本シリーズの17本目の動画です [ヴィンセント・ナイト博士](http://bit.ly/186ai3Z) カーディフ大学の。複数行にわたる大きな方程式や導出では、次の `\begin{align}` や `\end{align}` 整列した数式を正しく表示するためのコマンドを使います。ここではアンパサンド（`&`）コマンドを使って、方程式が常に望みどおりに揃うようにします。また、次の `\nonumber` 必要に応じて、方程式の途中のステップから式番号を削除するためのコマンドです。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/ja/to-2/54-how-to-write-multi-lined-equations-using-the-align-environment.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
