==========================================================

Let us do some math stuff on web:

$ m^2_a $ $ x^2 $,

\[ x^2 \]

$ \sum_{k=1}^\infty \frac{1}{k} $ and $\displaystyle \sum_{k=1}^\infty \frac{1}{k} $

\begin{align*}<br />
\int \ln(x) \;dx<br />
&= \int 1 \cdot \ln(x) \;dx \<br />
&= x \cdot \ln(x) - \int x \cdot \frac{1}{x} \;dx \<br />
&= x \cdot \ln(x) - x<br />
 \end{align*}
