A famous Astronomer, Aryabhatt invented the number zero but actually, the concept of zero was introduced earlier by Brahmagupt. The Brahmasphuta Siddhanta, a mathematical treatise by Brahmagupta, serves as a primary source for understanding the concept of zero in Ancient Indian mathematics.
 

• EVIDENCE : Brahmasphutasiddhanta, Chapter 18, Verse 21.
   

शून्यं शून्येन यदि शून्यं भागः स्याद् भाजकः।
आत्मधर्ममपीष्टं स्यात् प्रथमञ्च गुणः कृतः।
 

• Meaning: If zero is divided by zero, the result is zero. Divided by itself, it remains unchanged. Divided by any other number, the quotient is zero, and a number divided by zero is the first term of the proportion.
   

• The verse provides rules for the division involving zero. It states that zero divided by zero is zero, and if any number is divided by zero, the result is the first term of the proportion. Additionally, it emphasizes that zero divided by any other number is always zero.
  ​

The Brahmasphuta Siddhanta is a significant work in Indian mathematics and astronomy, and this verse reflects Brahmagupta's insights into mathematical concepts, including zero.
 

• Modern Science Connection: The concept of zero from Ancient Indian mathematics, as outlined by Brahmagupta, became foundational in the development of the Modern Science number system.
  ​

• Brahmagupta's articulation of zero in the Brahmasphuta Siddhanta laid the groundwork for the inclusion of zero in the modern number system. This historical connection emphasizes the profound influence of Ancient Indian mathematics on contemporary mathematical principles.
