going to be fooling around with themes and graphics for a while…
type latex shortcode directly into the visual editor
code from wp plugin page
so we are looking for latex mathmode syntax
here it is, the list of math symbols is corresponding to what i am getting experimentally, indispensable reference here -> https://en.wikibooks.org/wiki/LaTeX/Mathematics
anything referencing plugins is not directly applicable to the free wordpress version where plugins are not allowed (ie latex is provided automatically). some of this code that doesnt parse is copy pasted from these sites.
seems good -> https://wordpress.org/plugins/wp-latex/faq/
