It is widely spread that INDIANS invented zero what does it mean in fact many ancient civilization like GREEK, Babylonian, chines know about the zero and people from west argue that INDIANS did not invent zero but other civilizations have, the truth beyond this number is many civilizations just know this number but some did not even consider it as a number except Babylonian and Chines but Indians not only considered it as a number but worked on it and many ancient Indian mathematicians gave rules of zero
Rules of Brahmagupta
The rules governing the use of zero appeared for the first time in Brahmagupta’s book Brahmasputha Siddhanta (The Opening of the Universe), written in 628 AD. Here Brahmagupta considers not only zero, but negative numbers, and the algebraic rules for the elementary operations of arithmetic with such numbers. In some instances, his rules differ from the modern standard. Here are the rules of Brahmagupta:
- The sum of zero and a negative number is negative.
- The sum of zero and a positive number is positive.
- The sum of zero and zero is zero.
- The sum of a positive and a negative is their difference; or, if their absolute values are equal, zero.
- A positive or negative number when divided by zero is a fraction with the zero as denominator.
- Zero divided by a negative or positive number is either zero or is expressed as a fraction with zero as numerator and the finite quantity as denominator.
- Zero divided by zero is zero.
how ever some rules are wrong like Zero divided by zero is zero but and attempt was made to make calculations with it and later mathematician from India like Aryabhata, Madava gave the present day rules
Al-Khowarizmi Arab mathematician 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.
Indians worked on zero proved it as number and also proved it is not any ordinary number and gave rules to use zero in calculation this is reason behind why main stream media and mathematics scholars say Indians invented zero but we must remember that other civilizations where also aware of zero but could not prove it as number or did not accept it as number
the above image it is clear there is no zero even in India before 300BC but included after world, in fact the present days number system is from India as Indians number system is far more effective and robust than Roman or other number system the best example for Indian works is vedic maths which is written in vedas 3000 years ago but was not found until one guru from India wrote the separate book saying what he found in vedas
