TIL that emojis are not rotated 180 degrees in Arabic.

Also, you don't rotate numbers either, right? As in, if you were to embed 12345 in a sentence it would look like: This sentence talks about 54321, which is a number just under 00002.

Yes, numbers in Arabic are LTR even when they're used mid (RTL) sentence.

We'd also use https://en.wikipedia.org/wiki/Eastern_Arabic_numerals instead of the confusingly named (western) Arabic numbers 0123456789...

In a way it makes more sense to have the units come first, i.e. how the numbers are written in Arabic. Namely, when you do arithmetic you start with the units, so that in English (etc) when you compute 1234 + 5678 you cannot just start writing down digits, but you have to reserve space and work backwards.

This is intentional. They're called Arabic numerals for a reason - when they were imported to Europe to replace Roman numerals, they weren't flipped. This is why mental arithmetic is harder than it needs to be.

Nope. These numerals got to Arabic from India, where writing is LTR, and the digit order was unchanged during that transition and the transition to Europe. The order we use is the original order. They're called Hindu-Arabic numerals [1] for a reason, and in Arabic the equivalent [2] are called Indian numbers (أَرْقَام هِنْدِيَّة) [3]!

I didn't know, thanks for the correction :)

The Arabs must have switched it around then

[mkl]

No one switched it around, that's my point. The digit order everyone uses is the one best suited to mental arithmetic in LTR languages, where the most significant digit is first. See the book Secrets of Mental Math by Arthur Benjamin. It's also the best suited to getting a rough idea of the number quickly in LTR languages. That's because the digit order everyone uses was designed for LTR languages.
