If **TeX Math** support is enabled, this is an inline uppercase sigma: $\Sigma$, and this is the quadratic equation: $-b \pm \sqrt{b^2 - 4ac} \over 2a$
This is a **block of TeX** showing some matrix math:
$$
\begin{bmatrix}
a & b \\
c & d
\end{bmatrix}
\begin{bmatrix}
x \\
y
\end{bmatrix}
=
\begin{bmatrix}
ax + by \\
cx + dy
\end{bmatrix}
