Introduction to the Pahlavi numeral system and an effective approach to the calculus of Pahlavi numbers

Pahlavi numbers written by Pahlavi alphabet and including from an impressing numeral system, although we do not have a symbol for zero and at first glance it is non-positional but writing in such a way that it’s easy to determine the order of each number. Our approach into calculus of these numbers show that in summing up these numbers do not need a especial algorithm, also the number of products which an ancient child was preserved compare with other ancient numerals was much less. Moreover some of the large numbers (greater than ten thousand) have more than one display and this indicates the ability of this system.
