==An equation from the Gosia manual==

<pre><math>\xi_{kn}\equiv \frac{Z_1 Z_2 \sqrt{A_1}}{6.34977} 
\left( (E_p - s E_k)^{-1/2} - (E_p - s E_n)^{-1/2}\right)</math></pre>

renders as

<math>\xi_{kn}\equiv \frac{Z_1 Z_2 \sqrt{A_1}}{6.34977} \left( (E_p - s E_k)^{-1/2} - (E_p - s E_n)^{-1/2}\right)</math>



==An example from Wikipedia==

From the Wikipedia page on Riemann sums:

<pre>:<math>S = \sum_{i=1}^{n} f(y_i)(x_{i}-x_{i-1})</math></pre>

gives

:<math>S = \sum_{i=1}^{n} f(y_i)(x_{i}-x_{i-1})</math>
