Sometimes we need to use math in the post, Otherwise we can ask only general question and cannot go into details. Does somebody knows how we can add math expression into post?
You mean text like this
$$a=\frac{b^2)(2)$$

As you can see this approach does not work. I contacted support of the forum, but I not sure if they will answer

There is no need to use html tag to use mathjax. You right that using html tag is not secure for forum, However, you can add reference to mathjax into script which renders this page (this arXiv made this for example). In this case any text between \( and \) or between \[ and \] will be rendered as math expression. Using jpg ix not good idea for few reason. First of all one jpg is not enough. Also, if I want to put here \{\sqrt{\pi+2}\), I need to use html tag, because attachment will be somewhere else, but not at the place, where I need to show it. At this time I upload pdf file, however when we use some discussion like this question, it is strange that we cannot use math. Maybe it is good idea to discuss general relativity or quantum mechanics without any expression. or even better, to solve differential equation without seeing it. Help, I need to solve equation second derivative equal unknown function. Sounds good. After all this is forum for scientists,
Not sure what you meant with that comment Li Ma, can you give some more details? Thanx!
