我在KaTeX入门模板中插入了一个非常简单的主体，但它不起作用。为什么？我需要做什么来渲染身体？

<p>Inline math $p^{k}(1-p)^{n-k}$ is what this is</p>

查看代码的未优化版本，我发现了应用的默认设置。应使用以下delimeter：
$$\(\)\[\]
我能够通过将公式两侧的$更改为$$来使第一个公式起作用。
<p>1</p>
<p>Inline math $$p^{k}(1-p)^{n-k}$$ is what this is</p>
我能够通过将两侧的$更改为$$并在每行的末尾添加\来使第二个公式起作用。
<p>2</p>
<p>$$begin{aligned} \
x &= 2 \
&= frac{3}{2} \
end{aligned}$$
