this is a test

\( x = {-b \pm \sqrt{b^2-4ac} \over 2a} \)Some text:

\[ A_{2\times2} = \left[ {\begin{array}{cc} a_{11} & a_{12} \\ a_{21} & a_{22} \\ \end{array} } \right] \]

some more

- \(posterior probability = (\text{prior probability} \times likelihood) \div evidence \)
- \(posterior probability = \frac{\text{prior probability} \times likelihood} {evidence} \)
