Writing LaTeX formulas with MathJax on WordPress site: the simplest way (possibly without affecting header.php)?
I’m trying to add some math formula using LaTeX on the math part of my site, http://onlinemathbiz.com/linear-algebra/. I’ve already installed MathJax, and I can see it from my settings. However, when I try to edit the above site with Elemenator, I’m having problem to display the math.
Here’s what I’ve tried: I went on to edite it with Elementor, then first selected the widget “Text Editor” and then “custom HTML”, and tried typing the following:
$sqrt(2)$ [math] sqrt(2) [/math]
…but noen of them worked. I looked up on the internet, and I see that from here – https://docs.mathjax.org/en/stable/platforms/wordpress.html, we need to go to Appearences –> Editor (it doesn’t exist anymore, I guess now it’s called Theme Editor) —> go to the drop down list “Theme Files” —> select “header.php”. And then right before the end of the tag, we should insert
And doing so would “enable” MathJax with both TeX and MathML input. But I’m too scared to change the header.php, just in case it breaks my site. Is there a simoler solution? It’s important to note here that, I’m not making a post with math symbols in it, rather, I’m writing on http://onlinemathbiz.com/linear-algebra/.
I’d really appreciate a step by step answer with examples! Thanks in advance!!
