Kahandavaid

Kahandavaid, also known as the "Khandavaid" or "Khandavaidya," are a group of ancient Indian mathematicians and astronomers who lived during the 7th and 8th centuries CE. They are primarily known for their contributions to the field of mathematics, particularly in the development of the concept of zero and its use in arithmetic operations. The term "Kahandavaid" is derived from the Sanskrit word "khandana," which means "to break" or "to divide," reflecting their innovative approach to mathematical problems.

The most notable figure among the Kahandavaid is Brahmagupta, who is credited with the invention of the decimal system and the use of zero as a placeholder in arithmetic. His work, the "Brahmasphutasiddhanta," is a comprehensive treatise on mathematics and astronomy, which includes the first known use of zero in a mathematical context. Brahmagupta's contributions to mathematics were groundbreaking, as they laid the foundation for modern arithmetic and algebra.

Other notable Kahandavaid include Aryabhata, who is known for his work on trigonometry and the calculation of the Earth's circumference, and Bhaskara II, who made significant contributions to the field of algebra. These mathematicians and astronomers played a crucial role in the development of Indian mathematics and astronomy, and their work had a profound influence on the mathematical traditions of other cultures, including those of the Islamic world and Europe.
