most schools in urban india and a large number of the rest are 'english-medium'.. which means i learnt math in math class (in english) and learnt to count in hindi in hindi class.. but never had to solve a math problem in hindi
i am currently learning japanese and can agree about the numbers being syllablically small.. but this language has it own complexities - http://en.wikipedia.org/wiki/Japanese_counters which require a speaker to think a lot as well
