Paragraph

I wandered lonely as a cloud

That floats on high o'er vales and hills,

When all at once I saw a crowd,

A host, of golden daffodils;

Beside the lake, beneath the trees,

Fluttering and dancing in the breeze.

Mathematics

The mathematics powered by MathJax:

 \sum_{n=1}^\infty 1/n^2 = \frac{\pi^2}{6} 

When a \ne 0, there are two solutions to ax^2 + bx + c = 0 and they are

 x = {-b \pm \sqrt{b^2-4ac} \over 2a}
