+Jekyll Markdown Support doesn't includes mathematical equations. If one wants to write mathematical equations, integrating
+MathJax might be one possbile solution.
+
+If you are also using minima as the theme, you can allow mathematical syntax in your post pages by performing following steps:
+- Run `bundle info --path` followed by the name of the theme’s gem, e.g., `bundle info --path minima` for Jekyll’s default theme.
+This returns the location of the gem-based theme files. For example, the Minima theme’s files might be located in /usr/local/lib/ruby/gems/2.6.0/gems/minima-2.5.1 on macOS.
+- Open the themes directory, and find the `default.html` file under the `_layout folder`, `copy` that file into the _layouts folder of your project. If you have `no` `_layouts folder` under the `docs folder` in your project just like me, you might need to `create` that the _layouts folder.
+- `Append` the following scirpts tag into the `default.html` file
+
+{% highlight html %}
+<script type="text/javascript"
+    src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.3/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
+</script>
+{% endhighlight %}
+
+Now your default.html file under the _layouts folder might look like this:
+
+![Defaul.html](/berrywhj.github.io/assets/img/defaul-html.png)
+
+
+Then your post pages should be able to render mathematical equations properly.
