Example of an equation in a new line with $$ symbol
space at the beginning
\[a^2 + b^2 = c^2\]and this one with \begin{equation} environment
\begin{equation} \sum_{1}^{n} i = \dfrac{n(n+1)}{2} \end{equation}
An equation with cases
\[f(x)= \begin{cases} \frac{x^2-x}{x}& \text{if } x\geq 1\\ 0 & \text{otherwise} \end{cases}\]Another one
\[f(x)= \left\{ \begin{array}{ c l } \frac{x^2 - x}{2} & \quad \textrm{if } x \geq 1 \\ 0 & \quad \textrm{otherwise} \end{array} \right.\]Matrix using array
