I think it's a pretty big jump to say that this language difference is why Asians are often better at math. Maybe it is a contributing factor, particularly in younger grades when students are just learning arithmetic... but at some point, know how to do arithmetic. I'd make a guess that education style and social factors have a lot more to do with it.
