Recently, I was trying to add a few mathematical equations in the bolg posts. However, the equations were not working well. I looked for some tutorials, and found the following solutions:

  1. Add the following to the _includes/scripts.html

     <script type="text/javascript" async
     <script type="text/x-mathjax-config">
          extensions: ["tex2jax.js"],
          jax: ["input/TeX", "output/HTML-CSS"],
          tex2jax: {
            inlineMath: [ ['$','$'], ["\\(","\\)"] ],
            displayMath: [ ['$$','$$'], ["\\[","\\]"] ],
            processEscapes: true
          "HTML-CSS": { availableFonts: ["TeX"] }

    it says that if the mathjax is enabled in the pages, it will render the equations using the package. And based on this blog post, it became easier to use usual formats and notations we use in latex.

  2. Add mathjax: true in the default post configuration section of the _config.yml file as follows:

     # Defaults
       # _posts
       - scope:
           path: ""
           type: posts
           layout: single
           author_profile: true
           read_time: true
           comments: true
           share: true
           related: true
           mathjax: true

    check the last line, I have enabled mathjax as true.

And, now you are good to go. If you need to check the configuration files, you can visit my repository to see how I configured.

A few suggestions:

  • Use \vert as the pipe symbol rather than using | within the math expressions. Sometimes it does not work.
  • I prefer $ $ for inline expression (math within paragraph)
  • Other than that, you can use $$ $$ for equations that are not within the paragraphs.

That’s it! Have a good day.
