## Examples

- Inline math: $E = mc^2$
- Block math:

$$
\begin{equation}
\sum_{i=1}^{k+1} i = \left(\sum_{i=1}^{k} i\right) + (k+1)
\end{equation}
$$

$$
\begin{equation}
= \frac{k(k+1)}{2} + k + 1
\end{equation}
$$

$$
\begin{equation}
= \frac{k(k+1) + 2(k+1)}{2}
\end{equation}
$$

$$
\begin{equation}
= \frac{(k+1)(k+2)}{2}
\end{equation}
$$

$$
\begin{equation}
= \frac{(k+1)((k+1)+1)}{2}
\end{equation}
$$
