The sout tag works perfect in the \sout{main text area} but not inside the equations.
$list = $[1, \sout{2}, 3, \sout{4}, 5, \sout{6}, 7, \sout{8}, 9, \sout{10}$]$
Any clue?
\end{document}
It looks like the \sout doesn't work inside a math env. You can try doing something like this, which works:
\documentclass{article}
\usepackage{ulem}

Any clue?
\end{document}
If anyone's still interested, I just found out about the cancel package, which allows you to strike your text in math mode in a few different ways. It's not horizontal, though -- only diagonal, which in my case is much better.

Pretty much any non-math-mode command can be used inside mathmode by putting it within a \text{} environment, e.g.:
\documentclass{article}
\usepackage{ulem}
\begin{document}

\[ list = [1, \text{\sout{2}}, 3, \text{\sout{4}}, 5, \text{\sout{6}}, 7, \text{\sout{8}}, 9, \text{\sout{10}}] \]
Any clue?
\end{document}
And if you'd like to be able to use strike-out without having ulem redefine how \emph{} works, use \usepackage[normalem]{ulem}.

看起来
\sout在数学环境中不起作用。你可以尝试做这样的事情，它有效：

如果有人仍然感兴趣，我刚刚发现了取消套餐 ，它允许您以几种不同的方式在数学模式下删除文本。不过，它不是水平的——只是对角线，就我而言，这要好得多。

如果您需要在数学模式下保留删除线（例如，保留数学字体），请尝试：
那么
您需要 amsmath 和 ulem。
（来自此处的解决方案。）
If you need to keep the strikeout in Math mode (e.g., to keep Math fonts) try:
then
you need amsmath and ulem.
(Solution from here.)
几乎任何非数学模式命令都可以在数学模式中使用，只需将其放入
\text{}环境中即可，例如：如果您希望能够使用删除线 如果没有
