Quipu, a knotted cord device, used in the Inca Empire and its predecessor societies in the Andean region to record accounting and other digital data, is encoded in a base ten positional system. Zero is represented by the absence of a knot in the appropriate position. The zero function (or zero map) on a domain D is the constant function with 0 as its only possible output value, i.e., the function f defined by f( x) = 0 for all x in D. The zero function is the only function that is both even and odd. A particular zero function is a zero morphism in category theory; e.g., a zero map is the identity in the additive group of functions. The determinant on non-invertible square matrices is a zero map. Many animals can get through the first three steps. But the last stage, the most difficult one, is “reserved for us humans,” Nieder says.

ISBN 978-0-486-22332-2.We humans might have only come to understand zero as a number 1,500 years ago. What the experiments on bees and monkeys show us is that it’s not just the work of our ingenuity. It’s also, perhaps, the culminating work of evolution. When zero is added to a number or subtracted from a number, the number remains unchanged; and a number multiplied by zero becomes zero. Greeks seemed unsure about the status of zero as a number. Some of them asked themselves, "How can not being be?", leading to philosophical and, by the medieval period, religious arguments about the nature and existence of zero and the vacuum. The paradoxes of Zeno of Elea depend in large part on the uncertain interpretation of zero. [18] Example of the early Greek symbol for zero (lower right corner) from a 2nd-century papyrus

There can be confusion between 0- and 1-based indexing; for example, Java's JDBC indexes parameters from 1 although Java itself uses 0-based indexing. [71] Null values and the nullable type". IBM. 12 December 2018. Archived from the original on 23 November 2021 . Retrieved 23 November 2021. In regard to services, sending a null value as an argument in a remote service call means that no data is sent. Because the receiving parameter is nullable, the receiving function creates a new, uninitialized value for the missing data then passes it to the requested service function. British-owned cable manufacturer XLCC is planning to build the UK’s first factory making high-voltage undersea cables in Ayrshire to help meet demand. Production could begin as early as 2026. Zero also represents the absence of any negative or positive amount. For example, if you have 3 oranges and add zero oranges to that, you still have 3 oranges. Imagine trying to divide 12 oranges into zero groups—it’s not possible! There has to be at least one group.Seife, Charles (1 September 2000). Zero: The Biography of a Dangerous Idea. Penguin. p.39.

The Mesoamerican Long Count calendar developed in south-central Mexico and Central America required the use of zero as a placeholder within its vigesimal (base-20) positional numeral system. Many different glyphs, including the partial quatrefoil were used as a zero symbol for these Long Count dates, the earliest of which (on Stela 2 at Chiapa de Corzo, Chiapas) has a date of 36BC. [a] As a numerical digit, 0 plays a crucial role in decimal notation: it indicates that the power of ten corresponding to the place containing a 0 does not contribute to the total. For example, " 205" in decimal means two hundreds, no tens, and five ones. The same principle applies in place-value notations that uses a base other than ten, such as binary and hexadecimal. The modern use of 0 in this manner derives from Indian mathematics that was transmitted to Europe via medieval Islamic mathematicians and popularized by Fibonacci. It was independently used by the Maya. Keith Anderson, boss of Scottish Power, has warned that power companies and ministers will have their work cut out getting households to accept what will be a “colossal” increase in visible electricity infrastructure.

Struik, Dirk J. (1987). A Concise History of Mathematics. New York: Dover Publications. pp. 32–33. " In these matrices we find negative numbers, which appear here for the first time in history." Zero has been proposed as the atomic number of the theoretical element tetraneutron. It has been shown that a cluster of four neutrons may be stable enough to be considered an atom in its own right. This would create an element with no protons and no charge on its nucleus. Pannekoek, Anton (1961). A History of Astronomy. George Allen & Unwin. p.165. ISBN 9780045200023. OCLC 840043. Exponentiation: x 0 = x / x = 1, except that the case x = 0 is considered undefined in some contexts. For all positive real x, 0 x = 0. The Italian mathematician Fibonacci ( c. 1170– c. 1250), who grew up in North Africa and is credited with introducing the decimal system to Europe, used the term zephyrum. This became zefiro in Italian, and was then contracted to zero in Venetian. The Italian word zefiro was already in existence (meaning "west wind" from Latin and Greek Zephyrus) and may have influenced the spelling when transcribing Arabic ṣifr. [4] Modern usage
