LaTeX（LATEX，音译“拉泰赫”）是一种基于ΤΕΧ的排版系统，由美国计算机学家莱斯利·兰伯特（Leslie Lamport）在20世纪80年代初期开发，利用这种格式，即使使用者没有排版和程序设计的知识也可以利用TeX所提供的强大功能，生成很多具有书籍质量的印刷品。LaTeX对于生成复杂表格和数学公式表现得 1078 How does one insert a "\" (backslash) into the text of a LaTeX document? And how does one insert a "~" (tilde)? (If you insert \~, it will give you a tilde as an accent over the following letter. All this just means that they are not promising that $$ will always work. LaTeX still supports it for one reason or another, but the "proper" one to use, as defined in the specifications, is \[ \]. ) I believe \backslash may be used in math formulae, but not into text itself. And the top answer could easily edited to reflect also math mode. Answers deal already with it in math mode. When using LaTeX, can I just use $:=$, or do I need to do something special? 必须声明： 用LaTeX不是为了装X，而是为了方便 （至于你是不是装X，我真不知道）。 LaTeX能做的Word（和PPT）肯定能做，而Office系列也远比我们想象的要强大。 我认为用LaTeX不分什么人或者职业，只分什么场合，外加个人爱好。毕竟工具（LaTeX）只是为了提高效率，而非拿来恶心自己。不同的场合需要 The other famous tilde question could be made a bit more general and canonical by changing it to mean both text and math mode.

So it is technically possible (though unlikely in the near future), that compatibility with $$ is removed from LaTeX and lots of your documents Sometimes the symbol := is used to denote a definition. I think this would be better than making near-duplicates distinct, so I think the dupe vote of @doncherry would be good.
