The math delimiters are $$...$$ for displayed math (equation on a separate line), and \(...\) or [math] ... [/math] for in-line math (equation embedded in text paragraph).

Example 1: Algebra
The solutions to quadratic equation \(ax^2 + bx + c = 0\) are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$

The solutions to quadratic equation \(ax^2 + bx + c = 0\) are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$


Example 2: Complex Numbers
\begin{equation*}
e^{\pi i} + 1 = 0
\end{equation*}

\begin{equation}
e^{\pi i} + 1 = 0
\end{equation}


Example 3: Calculus
\begin{equation}
\int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15}
\end{equation}

\begin{equation}
\int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15}
\end{equation}


Example 4: Linear Algebra
$$ A_{i,j} = \begin{bmatrix}
a & b \\
c & d
\end{bmatrix} $$

$$ A_{i,j} = \begin{bmatrix}
a & b \\
c & d
\end{bmatrix} $$


Example 5: Continued Fractions
\begin{equation}
x = a_0 + \cfrac{1}{a_1
+ \cfrac{1}{a_2
+ \cfrac{1}{a_3 + \cfrac{1}{a_4} } } }
\end{equation}

\begin{equation}
x = a_0 + \cfrac{1}{a_1
+ \cfrac{1}{a_2
+ \cfrac{1}{a_3 + \cfrac{1}{a_4} } } }
\end{equation}

    This is a very nice feature to have

    Can you give more detailed instructions in using latex?

    There are so many good books (intro to advanced) and online wikis. Please take a look at them.
