# Start to learn LaTex

It might be necessary for me to use math equation in Markdown and start to learn LaTex.

# How to Use LaTex in GitHub Markdown

GitHub markdown seems not to support LaTex

So, we should:

- use Online LaTeX Equation Editor - create, integrate and download
- generate equation URL
- embet it as
`img`

in the`*.md`

file.

# Let’s get started

When using equation in LaTex file, we can use 3 styles.

`$ <equation> $`

`\[ <equation \]`

`\begin{equation} <equation> \end{equation}`

The first syntax is *inline* style, and the rest is *block* style.

The difference between 2. and 3. is that 2. is NOT add equation NUMBER and 3. does.

But I think my purpose to use LaTex is simply embedding math equation in Markdown, then these things I learned here is not so important.

## Example

```
\begin{documentation}
This is a sample equation in LaTex.
\[
E = mc^{2}
\]
\end{documentation}
```

generates:

This is a sample equation in Latex.

# And next

Fortunately the online editor is really helpful to generate equation without knowledge of LaTex literal, I’ll learn it gradually when needed.
