'''Positional notation''' or '''place-value notation''' is a method of representing or [[encoding]] [[number]]s.

== Description ==

Positional notation is distinguished from other notations (such as [[Roman numerals]]) for its use of the same symbol for the different [[orders of magnitude]] (for example, the "ones place", "tens place", "hundreds place").

This greatly simplified [[arithmetic]] leading to the rapid spread of the notation across the world.

== Base ten ==

With the use of a [[radix point]] (decimal point in base-10), the notation can be extended to include [[fraction (mathematics)|fraction]]s and the numeric expansions of [[real number]]s.

It developed from the [[Hindu–Arabic numeral system]], and is the most commonly used system in the world today for most calculations.

== Base sixty ==

The [[Babylonian Numerals|Babylonian numeral system]], base-60, was the first positional system developed, and is still used today to count [[time]] and [[Angle (geometry)|angles]].
