# LaTeX on the Web

*October 2012*
I have only started playing with it, but MathJax seems like a really nice tool to display math in web pages that is typeset using LaTeX syntax. There are a couple of small differences from a normal LaTeX document.

- The start and end $$ for a block equation (or any other delimiter) need to be on the same line.

## A little test of MathJax in action

When $a \ne 0$, there are two solutions to $ax^2 + bx + c = 0$ and they are $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
