## Example

Simple, Inline Equations

You can do a simple inline equation by using $an equation here$.

For example, you might do

$\lim\limits_{n \to \infty} \frac{1}{2^n} i\bar z$


which, if we put a little fake text around it, gives

Numbered, Centered Equations

When writing papers or other documents, it is sometimes preferable to have your equations centered and numbered, as opposed to in-line. Then, use the and commands.

For example, if we use the code

$$\lim\limits_{n \to \infty} \frac{1}{2^n} i\bar z$$


And add a little text around it, we get

You can remove the numbering of the equation by using \begin{equation*} and \end{equation*}.

For example, if we use the code

\begin{equation*}
\lim\limits_{n \to \infty} \frac{1}{2^n} i\bar z
\end{equation*}


and add a little text around it, we get

(though it should be noted you have to use the amsmath package for this).
