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](https://dsp.stackexchange.com/)?

When enabled this will render as a formula:

$$\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}$$
