Do users of RTL languages adopt an LTR standard for mathematics (in the same way they often do when using LTR words or phrases in RTL text)? Non-mathematician here. There is a discussion on this forum titled "Is “applying similar operations from left to right” a convention or a rule that forces us to mark one answer wrong?" I found it trying to answer a question I have. I could not comment as I am new here (trolling protection I guess) 
My interest is software localisation. My question is whether mathematics is globally written Left to Right (LTR). i.e. do those substantial countries that use a RTL languages adopt an LTR standard for mathematics (in the same way they often do when using LTR words or phrases). 
Note that I am not asking what is mathematically correct (i.e. use parenthesis properly) - I am asking what is commonly actually done? 
Thanks

Just put in some parentheses, and then you don't have to worry about the LTR-vs-RTL issue. The expression $(a-b)-c$ means the same thing everywhere.
