In a positional number system the value of each digit is determined by its position. For example we use n as the base for our number system. For any number in this system each digit to the left is equal to n times the position to the right; each each digit to the right is equal to the position to the left divided by n. The decimal system is an example of a positional number system with the base of 10.

Non-positional number systems' numbers can be represented by different symbols. The Roman number system is an example because each numeral in the system represent each level of magnitude by a different symbol.
