### Math

I was experimenting with the new MathML, Markup Language for Displaying Equations in your browser.

There are a lot of different ways, apparently, of displaying equations. Most of them are JavaScript libraries[3] [4] that have been written.

I'm opting for "a standard", described at [1].

Thank heavens that it is possible to use MathML (3.0) without having to use html+xml and other requirements like in MathML 2.0. [2]

Unfortunately, it's support in browsers is still sorely lacking, for example Long Division is one of the new things in MathML, and it is either not well supported, or I am doing something seriously wrong.

# Examples

$x=\frac{-b±\sqrt{{b}^{2}-4ac}}{2a}$

## Long Division

$٣#x0664;٣٥٫٣١٣٠٦١٢١٠٩١٦١٥١٫٠٩١$

Well, the long division example shows in my browser as utter junk. I hope someone else has more luck in viewing. Let me know. The examples in [5] also show non-working long division.
