[github] How to show math equations in general github's markdown(not github's blog)

It ’s 2020 now, let me summarize the progress of the mathematical formula rendering support of source code repository hosts.

GitHub & Bitbucket

GitHub and Bitbucket still do not support the rendering of mathematical formulas, whether it is the default delimiters or other.

Bitbucket Cloud / BCLOUD-11192 -- Add LaTeX Support in MarkDown Documents (BB-12552)

GitHub / markup -- Rendering math equations

GitHub / markup -- Support latex

GitHub Community Forum -- [FEATURE REQUEST] LaTeX Math in Markdown

talk.commonmark.org -- Can math formula added to the markdown

GitHub has hardly made any substantial progress in recent years.

GitLab

GitLab is already supported, but not the most common way. It uses its own delimiter.

This math is inline $`a^2+b^2=c^2`$.

This is on a separate line

```math
a^2+b^2=c^2
```

Who supports the universal delimiters?
