# MathJax tests

MathJax is an open source JavaScript display engine for mathematics that works in all browsers. Some examples of what it can do are provided below. Oh, and I want to to point out how very awesome is it that the markdown processor kramdown used on Nintoku supports math natively.

## Inside p tag

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

## Inside span tag

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

## Inside div tag

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

## Not in a tag

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

This is really cool!
