How to include math equations

To add math equations to your Blogger blog, you need to edit the HTML code of your Blogger post.

What seems to work is to copy this line, for example, 

<img src="https://render.githubusercontent.com/render/math?math=A = \begin{bmatrix}G B\\C D\end{bmatrix}">  

into the html view in the correct spot, and you get:

end of test.

So the above seemed to only work for this equation and failed when I tried other equations. 

Now, I think a good work around is to use latex2png and insert an image of the equation you want.
