An example: \((a + b)^2 = a^2 + 2ab + b^2\).

We get the above from below.

\begin{align} (a + b)^2 & = (a + b)(a + b) \\ & = a^2 + ab + ab + b^2 \\ & = a^2 + 2ab + b^2 \end{align}

We find the value of an interesting integral: \begin{equation} \int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15}. \label{eq:sample} \end{equation} To find the above equation \eqref{eq:sample}, we solve....
