EASSY ABOUT MATHEMATIRUON BRAMHAGUPTA

Answer 1

Brahmagupta was born c. 598, in Bhillamala, which was located in Northwestern India. The suffix "-gupta" probably indicated that the family belonged to the Vaisya caste (made up of mostly farmers and merchants).
He likely lived the majority of his life in Ujjain, India, which at the time was the center of Hindu astronomy and mathematics. There he had access to the best observatory in India as well as the writings of many great scientists and mathematicians who came before him, such as Hero of Alexandria, Ptomely, Diophantus and Aryabhata. In his own work he drew heavily from these sources and often corrected their mistakes.
At the age of 30, Brahmagupta wrote his first book, Brahma Sphuta Siddhanta. In 25 chapters this work explains much of his work in astronomy and mathematics. One of his greatest contributions that was revealed with the Brahma Sphuta Siddhanta was the defining of zero. He defined it as the result of subtracting a number from itself. Some of the properties he listed follow:
When zero is added to a number or subtracted from a number, the number remains unchanged; and a number multiplied by zero becomes zero.
He also gave rules for zero in terms of fortunes, which represent positive numbers, and debts, the negative numbers, as well as fortunes related to debts:

Answer 2

Brahmagupta was one of the famous Indian mathematicians and astronomers. He was the first mathematician who described the Zero and Negative Numbers. He wrote two main books on mathematics and astronomy in the Sanskrit language which called ‘Brahmasphutasiddhanta’ and ‘Khandakhadyaka’. Such a great Mathematician was born in 598 CE in Bhinmal, the Indian state of Rajasthan at present. The King Vyaghramukha was the ruler of Bhinmal and made Brahmagupta as the head of the astronomical observatory in Ujjain. In those days the Ujjain was the destination to all the mathematician and astronomers.  Especially, the ‘Brahmasphutasiddanta’ discussed the loopholes of his contemporary mathematician’s theories. This book has 24 chapters and 1008 Sanskrit Verses. This book also discussed the mathematical chapters of geometry, trigonometry, algebra and algorithmics. At the age of 67, he wrote another book ‘Khanda-Khadyaka’ discussed the astronomy.
