It is India that invented zero as a written digit in the decimal place value notation during the Gupta period. But now let’s dig deeper into this invention and its history of mathematics and global acceptance in the world.
Zero is a number and the numerical digit used to represent that number in numerals. It fulfils a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems. Names for the number 0 in English include zero, nought (UK), naught (US), nil, or—in contexts where at least one adjacent digit distinguishes.
Zero is the integer denoted “0” that, when used as a counting range, method that no objects are present. It is the handiest integer (and, in truth, the simplest actual quantity) that is neither negative nor positive. A range that isn’t always 0 is stated to be nonzero.
Zero is a surprisingly recent development in human history. In fact, this ubiquitous symbol for “nothing” didn’t even find its way to Europe until as late as the 12th century. Zero’s origins most likely date back to the “fertile crescent” of ancient Mesopotamia.
Zero within the Americas
Six hundred years later and 12,000 miles from the metropolis, the Mayans developed zero as a placeholder around A.D. 350 and used it to denote a placeholder in their elaborate calendar systems. Despite being extremely virtuoso mathematicians, the Mayans ne’er used zero in equations, however. Kaplan describes the Mayan invention of zero because of the “most hanging example of the zero being devised completely from scratch.”
Who invented zero in India?
Some students assert that the Babylonian idea wove its means all the way down to Bharat, but others, together with those at the Zero Project, provide Indians credit for developing numerical zero severally. “We square measure of the read that in ancient Bharat square measure found various questionable ‘cultural antecedents’ that create it plausible that the mathematical zero digits were fabricated there,” aforementioned Gobets, whose organization consists of teachers and graduate students dedicated to learning the event of zero in Bharat.
“The Zero Project hypothesizes that mathematical zero (‘shunya’, in Sanskrit) might have arisen from the contemporaneous philosophy of emptiness or Shunyata,” aforementioned Gobets. If philosophical and cultural factors found in Bharat were necessary to the event of zero as a mathematical idea, it might make a case for why alternative civilizations didn’t develop zero as a mathematical idea, aforementioned van der Hoek.

According to the book “The Crest of the Peacock, Non-European Roots of arithmetic,” by Dr. George Gheverghese Joseph, the idea of zero 1st appeared in Bharat around A.D. 458. Joseph suggests that the Indic word for zero, śūnya, meant “void” or “empty” and derived from the word for growth, combined with the first definition found within the Samhita of “lack” or “deficiency.” The spinoff of the 2 definitions is Śūnyata, a Buddhist philosophical system of “emptiness,” or evacuation of one’s mind from impressions and thoughts.
“From this philosophy, we predict that a numeral to use in mathematical equations developed,” aforementioned van der Hoek. “We square measure searching for the bridge between Indian philosophy and arithmetic.”
“Zero and its operation square measure 1st outlined by [Hindu uranologist and mathematician] Brahmagupta in 628,” aforementioned Gobets. He developed a logo for zero: a dot beneath numbers. “But he, too, doesn’t claim to possess fabricated zero, that presumptively should are around for a few time,” Gobets more.
An inscription on a temple wall up Gwalior, India, dates back to the ninth century and has been thought about as the oldest recorded example of a zero, in keeping with the University of Oxford. Another example is the Associate in Nursing ancient Indian scroll referred to as the Bhakshali manuscript. Discovered in a field in 1881, researchers thought it additionally had originated within the ninth century. However, recent geological dating has disclosed that it had been in all probability written within the third or fourth century, which pushes the earliest recorded use of zero back five hundred years.
Marcus du Sautoy, a prof of arithmetic at the University of Oxford, said, “Today we tend to take it as a right that the idea of zero is employed across the world and could be a key building block of the digital world. however, the creation of zero as variety in its claim, which evolved from the placeholder dot image found within the Bakhshali manuscript, was one of the best breakthroughs in the history of arithmetic.
“We currently recognize that it had been as early because of the third century that mathematicians in Bharat planted the seed of the concept that will later become therefore basic to the trendy world. The findings show however vivacious arithmetic are within the Indian sub-continent for hundreds of years.”
History of zero in China
The Sūnzĭ Suànjīng, of unknown date, however, estimated to be dated from the first to fifth centuries AD, and Japanese information dated from the 18th century, describes how the c. 4th century BC Chinese language counting rods system enabled one to carry out decimal calculations. As famous in Xiahou Yang’s Suanjing (425–468 AD) states that to multiply or divide a quantity by 10, 100, 1000, or 10000, all one must do, with rods on the counting board, is to move them forwards, or again, by 1, 2, 3, or four locations, Based on A Historical past of Arithmetic, the rods “gave the decimal illustration of a quantity, with an empty house denoting zero. The counting rod system is taken into account as a positional notation system.
In AD 690, Empress Wu promulgated Zetian characters, certainly one of which was “〇”. The image zero for denoting zero is a variation of this character.
Zero was not handled as a quantity at the moment, however as a “vacant place”. Qín Jiǔsháo’s 1247 Mathematical Treatise in 9 Sections is the oldest surviving Chinese language mathematical textual content utilizing a spherical image for zero. Chinese language authors had been acquainted with the thought of unfavourable numbers by the Han Dynasty (2nd century AD), as seen in The 9 Chapters on the Mathematical Artwork.
History of zero in maths
Sumerian scribes used spaces to denote absences in number columns as early as 4,000 years ago, but the first recorded use of a zero-like symbol dates to sometime around the third century B.C. in ancient Babylon.
The Babylonians employed a number system based on values of 60, and they developed a specific sign—two small wedges—to differentiate between magnitudes in the same way that modern decimal-based systems use zeros to distinguish between tenths, hundreds and thousandths. A similar type of symbol cropped up independently in the Americas sometime around 350 A.D., when the Mayans began using a zero marker in their calendars.
These early counting systems only saw the zero as a placeholder—not a number with its own unique value or properties. A full grasp of zero’s importance would not arrive until the seventh century A.D. in India. There, the mathematician Brahmagupta and others used small dots under numbers to show a zero placeholder, but they also viewed the zero as having a null value, called “Sunya.”
Brahmagupta was also the first to show that subtracting a number from itself results in zero. From India, the zero made its way to China and back to the Middle East, where it was taken up by the mathematician Mohammed ibn-Musa al-Khowarizmi around 773. It was al-Khowarizmi who first synthesized Indian arithmetic and showed how the zero could function in algebraic equations, and by the ninth century, the zero had entered the Arabic numeral system in a form resembling the oval shape we use today.
The zero continued to migrate for another few centuries before finally reaching Europe sometime around the 1100s. Thinkers like the Italian mathematician Fibonacci helped introduce zero to the mainstream, and it later figured prominently in the work of Rene Descartes along with Sir Isaac Newton and Gottfried Leibniz’s invention of calculus. Since then, the concept of “nothing” has continued to play a role in the development of everything from physics and economics to engineering and computing.
The denotation of Zero in different cultures
- The Mayans used an eyelike character [top left] to denote zero.
- The Chinese started writing the open circle we now use for zero.
- The Hindus depicted zero as a dot.
- The Babylonians displayed zero with two angled wedges (middle).
