How to Use MathJax on Wordpress

Created at 2016-05-03T05:17:56.000Z
Instead of installing any kinds of plugin, I added mathjax script on *header.php* directly.
Here is a relevant change: hi-ogawa/wordpress-revisr (commit: 999b7d)

### Demo

**Before:**

```
Block Codes:
\\[1 + 1 = 100\\]
$$ F_{S, A}(X) = X^S + A $$
Inline Codes:
- bla ... \\(x_0 + x_1 = y^{-9}\\) bla...
- bla ... $x_0 + x_1 = y^{-9}$ bla...
```

**After:**

Block Codes:

\[1 + 1 = 100\]

$$ F_{S, A}(X) = X^S + A $$

Inline Codes:

bla ... \(x_0 + x_1 = y^{-9}\) bla...

bla ... $x_0 + x_1 = y^{-9}$ bla...

Since Wordpress Editor doesn't recognize backslash `\`

itself, you need to escape with another backslash. That's why you see `\\`

in above example.
