prime numbers are invented by srinivasan ramanujan, an Indian mathematician.
it was around the time of christ.Although the first set of rules for dealing with negative numbers was stated in the 7th century by the Indian mathematician Brahmagupta, it is surprising that in 1758 the British mathematician Francis Maseres was claiming that negative numbers "... darken the very whole doctrines of the equations and make dark of the things which are in their nature excessively obvious and simple" .Maseres and his contemporary, William Friend took the view that negative numbers did not exist. However, other mathematicians around the same time had decided that negative numbers could be used as long as they had been eliminated during the calculations where they appeared.It was not until the 19th century when British mathematicians like De Morgan, Peacock, and others, began to investigate the 'laws of arithmetic' in terms of logical definitions that the problem of negative numbers was finally sorted out.However, there were references to negative numbers far earlier...In 200 BCE the Chinese number rod system (see note1 below) represented positive numbers in Red and Negative numbers in black. An article describing this system can be found here . These were used for commercial and tax calculations where the black cancelled out the red. The amount sold was positive (because of receiving money) and the amount spent in purchasing something was negative (because of paying out); so a money balance was positive, and a deficit negative.Negative intergers were accepted around the time of Christ.
In European notation a lakh is a unit in the Indian numbering system equal to one hundred thousand (100,000). Therefore 4 lakh = 400,000.However, the Indian notation (where one places the commas to group numbers) is different and a lakh is written as 1,00,000. Therefor in this notation 4 lakh = 1,00,000.
Oh, dude, writing out numbers in words is like the most thrilling thing ever! So, 18,000,000 INR in words would be... wait for it... "Eighteen million Indian Rupees." Boom! Mind blown, right? I know, I know, it's just too much excitement for one day.

The history of rational numbers goes way back to the beginning of historical times. It is believed that knowledge of rational number precedes history but no evidence of this survives today. The earliest evidence is in the Ancient Egyptian document the Kahun Papyrus. Ancient Greeks also worked on rational numbers as a part of their number theory. Euclid's elements dates to around 300 BC. Indian mathematicians also worked on rational numbers. This is documented in different texts but the most important is probably the Sthananga Sutra which dates back to around the second century BC.
The Fibonacci sequence is named after Italian mathematician Leonardo of Pisa, known as Fibonacci. His 1202 book Liber Abaci introduced the sequence to Western European mathematics, although the sequence had been described earlier as Virahankanumbers in Indian mathematics.

Because they come from the Hindu-Arabic numeral system developed by Indian mathematicians.
The inventor of the numeral system 0-9 is attributed to Indian mathematicians, particularly Aryabhata in the 5th century CE. These numbers were later introduced to the Western world by Arab mathematicians.

As an essential component of mathematics, the idea of real numbers is not credited to a single person. Several mathematicians and academics have contributed to the evolution of real numbers over the course of centuries. The concept of real numbers evolved progressively over time, including contributions from the Greeks, Egyptians, and Babylonians among other ancient civilizations. However, during the Renaissance and Enlightenment eras, mathematicians like RenΓ© Descartes, Pierre de Fermat, and Isaac Newton, among others, improved and codified the present understanding of real numbers, including their properties and notation. The introduction of the decimal system by Indian mathematicians in the 9th century was a significant turning point in the evolution of real numbers as it profoundly affected how numbers were represented and understood. for more information visit : webdigitalguru.in
