first off, i've never been to web development.

I'm developing my personal website where, for some purpose , i need to display some math figures. And somebody suggested me to use mathjax for this purpose. i tried it on my own. it works. but i see some font-size related issues.

Here is what i did.

I add the library using this :

```
<script type="text/javascript" async
src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-MML-AM_CHTML"> </script>
```

then i put the maths text in body section. like this

```
<body>
\(x={72^2-{\sqrt{53^2}}\over 25}\)
</body>
```

when i see it in the browser , it shows the maths figures but in very small font.

when i used the following , it showed it in the size what i want

```
<body>
$$x={72^2-{\sqrt{53^2}}\over 25}$$
</body>
```

So , here my question is : what is the difference between these two syntax

`\(x={72^2-{\sqrt{53^2}}\over 25}\) [syntax 1]`

`$$x={72^2-{\sqrt{53^2}}\over 25}$$ [syntax 2]`

And how to increase the font size using the [syntax 1]

thanks in advance.
