in this numerals 0 to 99 which is least repeat digit
until the most important number was invented in India! ---- it was possible to count up to 9 only, roman numerals were not adequate enough to do better easily, the advent of the number '0' made it possible to count up to millions and billions with ease.... Without this '0', computers and most electronics could not work since they rely on binary coding cosisting of 1's &'0's. So we can thank our Indian friends for inventing the number'0'.
