Hello,
The answer is yes, math equations are rtl when Arabic variable names and
numbers are used.
In case Greek or latin variable names are used, the equation will be ltr in
that case.

Thanks And Best regards,

Hi, Mohamed, all:


Just a question -- since what Mohamed said seems to contradict what Najib
said --
are math equations generally rtl when Arabic variable names and numbers are
used?
(Amit noted that in Hebrew, when Hebrew names are used, directionality can
be either rtl or ltr but otherwise it is ltr.)
And thus is it otherwise when Greek variable names are used with
Arabic-indic digits, that is, is it then ltr?

Or does math directionality vary with locale (one set of rules for North
Africa, another for Egypt)?

Thanks!

Best wishes,
