- In non-positional number system, each symbol represents the same value regardless of its position.In positional number system ,each symbol represents different value depending on the position they occupy in a number.
- In non positional number system,its very difficult to perform arithmetic with such a number system.In positional number systems were developed.

The number system now in commonest use worldwide is positional. Consider a number such as 924.37. The position of each digit in the number indicates how significant it is. The digit 9 represents 100s, the 2 10s, the 4 1s, and so on.The Roman number, or 'numeral' system, is non-positional. The value of a character in a number does not depend on its position only. Rather, the value of a character depends on what the character is and on neighbouring characters. Consider a number such as XLIV. In this case the 'X' means ten but only as a modifier for the 'L' which stands for fifty, so that the combination 'XL' means 40.

hieratic numerals did not form a positional system so the particular numerals could be written in any order.

The number system that we use today is the Hindu-Arabic numeral system and a 0 number is essential for positional place value purposes as for example it shows us that there is a difference between 27 and 207 but a 0 number is not needed in the Roman numeral system because the positional place value of its numerals are self evident as for example XXVII is 27 and CCVII is 207

Their are two types of number systems. 1. Non positional number systems 2. Positional number systems.

So as not to be shortchanged when handling money because there's a difference between $203 and $2003 and knowing the positional place value of numbers by means of the 0 symbol will prevent any mistakes.

In the non positional number system, the value of the number does not depend upon the position of "digits" used to represent the number. Unlike the positional number system, in non positional system every number, as a whole, is represented as a combination of certain specific symbols. Therefore, according to me, there is no such a notion of "digits" in the non positional system. The classic example of non positional number system is the Roman number system in which the numbers are represented by certain specific symbols: I for 1 II for 2 X for 10 XX for 20 etc.

I think you meant positional number system or Positional Notation. In computer science when we talk about positional notation where talking about the binary(base 2) and hexadecimal(base 16) system. So for the most part a positional number system is a counting system. We for example use a base 10 counting system.
