It is a normal form of an
equation in Iran. In Afghanistan, also a Persian speaking country, mathematical
notations are expressed the same way as in English.

don't know how is arabic mathematics but the picture is a normal form of an
equation in Persian

After asking Dan Brickley to forward my message, I was convinced to

join the list in order to formulate my request more specifically. As I

wrote before, the MathML group at W3C are looking at world-wide

mathematical notations, in order to find out if anything's missing in

the language. Right-to-Left writing is the first that came to our

minds so we spent some time already to look at Arabic, and we're going

to investigate Hebrew and others.

We found one example of persian mathematics that seemed to differ from

Arabic. It's at <
http://people.w3.org/maxf/tmp/limf.png>. I don't know

any of either Arabic or Persian, but I'm told the equation differs

from arabic in that the numbers are different. The limit operator is

also special in that it appears to be stretchable.

The central question really is: does Persian mathematical notation

have any such particularities that would make its layout different

from other languages, in particular right-to-left ones, and that would

then require special constructs in the MathML language?

Thanks for any insight,

Max.
