The Mayan numeral system was the system to represent numbers and calendar dates in the Maya civilization. It was a vigesimal (base-20) positional numeral system. The numerals are made up of three symbols: zero (a shell), [1] one (a dot) and five (a bar). For example, thirteen is written as three dots in a horizontal row above two horizontal ...
The shell glyph was used to represent the zero concept. The Long Count calendar required the use of zero as a place-holder and presents one of the earliest uses of the zero concept in history. On Maya monuments, the Long Count syntax is more complex.
The bar-and-dot counting system that is the base of Maya numerals was in use in Mesoamerica by 1000 BC; [306] the Maya adopted it by the Late Preclassic, and added the symbol for zero. [307] This may have been the earliest known occurrence of the idea of an explicit zero worldwide, [308] although it may have been later than the Babylonian ...
It is remarkable for being the oldest known usage of a Maya ordinal zero, [9] which symbol (graphically derived from the drawing of a sitting man, typically representing a king's crowning) appears two times, one to form the date "0 Yaxkin" from the first day of the seventh month of the festive year in Haab' calendar, and one to denote the Moon ...
List of Maya numerals from 0 to 19 with underneath two vertically oriented examples. The Mayas used a positional base-twenty numerical system which only included whole numbers. For simple counting operations, a bar and dot notation was used. The dot represents 1 and the bar represents 5. A shell was used to represent zero.
The Maya calendar consists of several cycles or counts of different lengths. The 260-day count is known to scholars as the Tzolkin, or Tzolkʼin. [5] The Tzolkin was combined with a 365-day vague solar year known as the Haabʼ to form a synchronized cycle lasting for 52 Haabʼ called the Calendar Round.
Zero was not treated as a number at that time, but as a "vacant position". [39] Qín Jiǔsháo's 1247 Mathematical Treatise in Nine Sections is the oldest surviving Chinese mathematical text using a round symbol ‘〇’ for zero. [40] The origin of this symbol is unknown; it may have been produced by modifying a square symbol. [41]
