This mostly scientific site will certainly contain a lot of questions and answers with mathematical formulae. Can we have MathJax enabled here like on similar Signal Processing?
When enabled this will render as a formula:
$$\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}$$
Here is the code to create the formula:
$$\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}$$
This will be rendered as follows:
