MD基本语法

Markdown是一种可以使用普通文本编辑器编写的标记语言，通过简单的标记语法，它可以使普通文本内容具有一定的格式。Markdown具有一系列衍生版本，用于扩展Markdown的功能（如表格、脚注、内嵌HTML等等），这些功能原初的Markdown尚不具备，它们能让Markdown转换成更多的格式，例如LaTeX，Docbook。Markdown增强版中比较有名的有Markdown Extra、MultiMarkdown、 Maruku等。这些衍生版本要么基于工具，如Pandoc；要么基于网站，如GitHub和Wikipedia，在语法上基本兼容，但在一些语法和渲染效果上有改动。

本站在写文章时候可参考以下markdown语法：

Math

$$
evidence\_{i}=\sum\_{j}W\_{ij}x\_{j}+b\_{i}
$$

$$
AveP = \int_0^1 p(r) dr
$$

When $a \ne 0$, there are two solutions to \(ax^2 + bx + c = 0\) and they are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$

$$evidence\mathrm{\_}i=\sum \mathrm{\_}jW\mathrm{\_}ijx\mathrm{\_}j+b\mathrm{\_}i$$

$$AveP={\int }_0^{1}p(r)dr$$

When $a\ne 0$, there are two solutions to (ax^2 + bx + c = 0) and they are

$$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}.$$
