Detailed explanation-1: -Indians invented zero and the number system, one of the greatest innovations in history. The decimal system, the value of pi, algebra, trigonometry, calculus and many mathematical concepts were all born in India.
Detailed explanation-2: -What is widely found in textbooks in India is that a mathematician and astronomer, Aryabhata, in the 5th century used zero as a placeholder and in algorithms for finding square roots and cube roots in his Sanskrit treatises.
Detailed explanation-3: -As well as giving us the concept of zero, Indian mathematicians made seminal contributions to the study of trigonometry, algebra, arithmetic and negative numbers among other areas. Perhaps most significantly, the decimal system that we still employ worldwide today was first seen in India.
Detailed explanation-4: -The first time we have a record of zero being understood as both a symbol and as a value in its own right was in India. About 650 AD the mathematician Brahmagupta, amongst others, used small dots under numbers to represent a zero.
