Math Testing

You can use math in-line, such as ${\displaystyle 8+4=12}$ and ${\displaystyle \frac{155}{12}=\frac{10}{2}}$.

Or you can use as paragraphs:

${\displaystyle \frac{155}{12}=\frac{10}{2}}$

${\displaystyle x^2+y^2=1}$

Or with a blockquote-like syntax:

${\displaystyle x_{1,2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}}$

Code is not translated: x = pi
