High Quality Content by WIKIPEDIA articles! Positional notation or place-value notation is a generalization of decimal notation to arbitrary base. These include binary (base 2) and hexadecimal (base 16) notations used by computers as well as the base 60 notation of Babylonian numerals. Indian mathematicians developed the Hindu-Arabic numeral system, the modern decimal positional notation, in the 9th century. Positional notation is distinguished from previous notations (such as Roman numerals) for its use of the same symbol for the different orders of magnitude (for example, the "one's place", "ten's place", "hundred's place"). This greatly simplified arithmetic and lead to the quick spread of the notation across the world.
