WordPress does not support Latex out of the box. You have to install a plugin to write mathematical equation like Calculous. Here are the steps to enable latex support-
- Install the “Mathjax-Latex” plugin from WordPres.org. You can either search the name from your WordPress admin dashboard or download the plugin directly from here https://wordpress.org/plugins/mathjax-latex/
- After you have activated the plugin, you can write a mathematical equation anywhere on your WordPress website. You just have to wrap the markup with
[\latex]. In some cases the [latex] shortcode might not work. In that case, you might need to use the alternatives such as
