### Aligning equations

If you want a sequence of aligned equations (often very useful for demonstrating algebraic manipulation or for plugging values into equations), use \begin{align*} ... \end{align*}. Separate lines with \\ and use & to mark where things should line up. Note: No dollar signs are needed when you use this method.

#### Example

This

\begin{align*}
a & = b \\
X &\sim {\sf Norm}(10, 3) \\
5 & \le 10
\end{align*}

produces

\begin{align*} a & = b \\ X &\sim {\sf Norm}(10, 3) \\ 5 & \le 10 \end{align*}
