The binary or base 2 numeral system is a positional system which uses only two symbols to represent a number: 1 and 0. It does not use the zero and is positional. The traditional system of counting on fingers is an example of unary numeration. The unary system is useful in processes of counting, like the scoreboard in a sport, or counting the number of people who enter a place, or the number of votes going out in an election, as it does not require amending previous results, only that one keep adding symbols for the later recount. It is base 5, and utilizes the digits from 0 to 4. It was developed based on the fact that humans have five fingers on each hand. It is one of the most ancient systems of numbering, also being the name of an ancient Roman coin of the same value.
