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,
C. E. Whitehead
