Entering mathematical statements using latex

[Adesh]

TL;DR Summary

Why different sites use different codes?

I have been to other forum sites too where we need to encode a mathematical statement like this \(\displaystyle ...\) , some sites use $...$ before and after the mathematical things and some sites like this great forum use [itex]...[itex]. Why it this so? The latex software like Texstudio, Texmaker etc. uses $$ sign. Some sites (or apps) even use `...` thing, why is this and what's the difference between all these?

This is because we use MathJax which is slightly different than LaTeX. The main difference is ## = [itex] instead of $, and that not all LaTeX style files are included. Of course I cannot answer the question for other sites.

StackExchange too uses MathJax, but there you have to use $ for inline math. I believe (could be wrong) MathJax can can be configured to identify ## instead of $ as inline math.

The latex software like Texstudio, Texmaker etc. uses $$ sign.

They use $ for inline math, and $$ for paragraph-style math.

Mathjax is the implementation of $\LaTeX$ in websites.

Can you please tell me what are \(\displaystyle ...\) tags used for? Many old websites use this tag.

Different websites have different ways of implementing $\LaTeX$. It is upto the website to decide how they want to trigger MathJax. Just like PF uses $\text{$}$for inline$\LaTeX##, some sites use \(\displaystyle ...\) tags. There is basically nothing more to explain.On a similar note, in PF, we can trigger monospace font using the BBCode [icode]. StackExchange, on the other hand, uses ```` characters to monospace font. This again depends on how the website wants to trigger the HTML tag <code>. Nothing more to explain.

Where bbcode tags are implemented on a bbs, typically they are used for triggering rendering of $\LaTeX$ code, just as PF uses##delimiters for that purpose.
