If you allow additive compounds, you can easily name all numbers without having an infinite amount of primes.

It's massively parallel, rewires itself constantly, functions on a holographic principle (even when damaged, parts can take over the functions of the non-functional parts) and works by deduction, induction and pattern-matching rather than algorithmically. Any comparison with an algorithmic behaviour will necessarily be a flawed one. That's also why I don't find it so weird that "quatre-vingt" wouldn't automatically be parsed by a French speaker, despite it being so transparent. "quatre-vingt" is just directly associated with the quantity, as a label, not as a formula that needs parsing each time. It wouldn't make sense for a computer that is more efficient at algorithmic behaviour, but makes complete sense for the brain, which is more efficient at memory recovery and pattern-matching. > [snip] > > As Adam remarked: > > >> They are some odd folk, those Livies! > > > > They are odd, yes. > > I'm left wondering whether the Livies are human at all and > not rather a race of robots. > > Indeed. I've wondered myself for quite a while now.

The reason could be different: contamination from Western methods of teaching maths, for instance (I was talking about Oman, which has a lot of Western influences. I don't know how Arabic people write numbers in other countries). What would be nice to know is whether this direction of writing numbers has always been like that, or whether it is a (relatively) modern development. In any case, Arabic people read numbers from right to left, which fits neatly with how they actually pronounce them. So for reading there is no inversion necessary (unlike, say, Germanic languages, including Old and Middle English, which put the units before the tens in speech).
