A little bit out of topic, but just wandering whether exists a proper LaTeX package to render “elementary math”.

I failed to find one so far (downgrading IE to IE9 + installing a plugin isn't really future proof). Possibly currently only MathPlayer supports it natively, and as you indicate that is not available in current IE however it's possible to transform the markup to mathml2 for rendering in other clients. The MathJax "content mathml" extension and the firefox mathml-mml3ff addon both work by using some XSLT of mine to translate the markup to mathml2 mtable. https://code.google.com/p/web-xslt/source/browse/trunk/ctop Most of that content mathml to presentation transformation has also been re-encoded in javascript to avoid the XSLT stage (which is very slow in chrome) although not currently the elementary math part, that shouldn't be hard to add, given some time. 2) Despite being XML, <mstack> relies on children order instead of named elements like <dividend>, <divisor>, <quotient>. What's the rationale behind this choice? Positional children are used quite a lot in the mathml design: mfrac msub etc also do not have named arguments.
