ASCIIMathML.js (ver 2.0): Translating ASCII math notation to MathML

<h4 align="center">
Would you or your students like to <i>easily</i> produce
<i>good-looking</i> math formulas on webpages<br/>
using a <i>simple</i> calculator-style syntax and your
own ASCII or HTML editor?
<br/>
Here is a free multi-platform solution (and if you prefer it,
LaTeX-style formulas also work).

<b>Let's test the ASCIIMathML.js translator on a simple example.</b>
</p>
<p>amath
<b>Example:</b> Solving the quadratic equation.
Suppose a x^2+b x+c=0 and a!=0. We first
divide by \a to get x^2+b/a x+c/a=0.
Then we complete the square and obtain x^2+b/a x+(b/(2a))^2-(b/(2a))^2+c/a=0.
The first three terms factor to give (x+b/(2a))^2=(b^2)/(4a^2)-c/a.
Now we take square roots on both sides and get
x+b/(2a)=+-sqrt((b^2)/(4a^2)-c/a).
Finally we subtract b/(2a) from both sides and simplify to get
the two solutions: x_(1,2)=(-b+-sqrt(b^2 - 4a c))/(2a)

<p>
If you are familiar with MathML, you can appreciate that this ASCII
input form is less verbose and more readable. If you are familiar with
TeX, this is still somewhat less cluttered. The aim is to have input
notation that is close to graphing calculator notation, so that
students are able to use it on webpages and in emails without having
to learn another specialized syntax.
</p>
<p>
For an explicit description of the input syntax see <a
href="asciimathsyntax.html">ASCIIMathML.js Syntax and List of
Constants</a>.

<p>
<b>Acknowledgements:</b> Many thanks to the numerous people who have
contributed to the fantastic MathML standard. Without such a
well designed standard, a project like this would be impossible.<br/>
Thanks to the many volunteers who implemented MathML in the
Gecko layout engine for Netscape7/Mozilla/Firefox.<br/>
Thanks to the people at Design Science for producing the excellent
MathPlayer plugin and making it freely available.<br/>
Finally, thanks to the designers and implementors of JavaScript. All
these tools work together fairly seemlessly to allow us to put
mathematical formulas on webpages in a convenient and inexpensive way.<br/>
And thanks to Andrew White for making a logo for ASCIIMathML (see below).
