Re: “Numbers: Roman, East Arabic and Arabic

Although the Romans written form of numeric values was clumsy, they were cognizant of a decimal place value system including a null value for any decade. This immediately apparent with the first look at a Roman bronze abacus which was the first example of a practical "pocket calculator". Have a look at this Wikipedia article. http://en.wikipedia.org/wiki/Roman_abacus
