# Math formulas in CMS

## Writing inline (LaTeX) math formulas anywhere on a static or dynamic page using MathJax.

CMS
Code
Integration

The script allows math formulas to be written anywhere within the HTML code. To start the inline math you use either a dollar sign $or you can use a slash and an open parentheses "/(". To end the inline math, you have another dollar sign or a back slash and a closing parentheses. Enclosing in double dollar signs put the math on a seperate line. So, let's get to it- First we add the MathJax JS library and the Polyfill.js dependency in our page <script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script> <script type="text/javascript" id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script> Copy Now we add the MathJax function to initiate the script and define what is a math formula: <script> MathJax = { tex: { inlineMath: [['$', '$'], ['\$$', '\$$']] }, }; </script> Copy If you need to use a dollar sign in the text, you can use a backslash before the dollar sign. "\$"

Dollar sign before and after:

$y=mx+1$

Parenthesis:

$$y=mx+2$$

Double Dollar Signs:

$$y=mx+3$$

Hard Bracket:

$y=mx+5$

In a sentence:
When $a \ne 0$, there are two solutions to $$ax^2 + bx + c = 0$$ and they are

$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$

When your bath soap bar gets too small to use, don't throw it away! open the next bar, and when you finish showering, stick the small old bar to the back of the new bar. Onces they both dry, they will become one.
