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 , there are two solutions to and they are

## 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 , there are two solutions to and they are

This is really cool!
