RPN Calculator use in Asia

[HP67]

I have no idea what this means. As far as I know (and I now live in Asia in a country that has a RTL language but I am not from here originally) people use normal calculators. At least I have never seen any calculator in a shop that strikes me as unusual. Anybody in tech has to have some minimal English ability and as far as I know most countries and places use normal numbers written LTR so... the only problems I am aware of is when they write doc in a RTL language it's annoying (and stupid) to have to shift for English acronyms. The word processors all figure out numbers and do the LTR automatically. Very dumb system AFAIC everybody should speak and write in English
