Let me make a test

This is an inline math :$\sum_{i=1}^nx_iy_i\leq\sqrt{\sum_{i=1}^nx_i}\sqrt{\sum_{i=1}^n y_i}$

This is in display math: $$\sum_{i=1}^nx_iy_i\leq\sqrt{\sum_{i=1}^nx_i}\sqrt{\sum_{i=1}^n y_i}$$

New line

\[\sum_{i=1}^nx_iy_i\leq\sqrt{\sum_{i=1}^nx_i}\sqrt{\sum_{i=1}^n y_i}\]

$\begin{tabular}{c|c|c}a&b&c\\d&e&f\end{tabular}$

$2x + 3 = \frac{1}{2}$
