The Hindus were generally highly imaginative, and their mathematics developed along such lines as the theory of numbers, geometry, and astronomy. However, the Hindu mind was primarily occupied with the arithmetical. Their aim was primarily not mathematical but religious. Mathematical parts refer to geometrical ideas and mensuration. The dating and origin of early Hindu mathematical works is even less certain than the Chinese.
Some claims are preposterous.
For example, the first edition of the Surya Siddhanta , or Knowledge from the Sun , of the Swami Press at Meerut, claims the work was compiled 2,165,000 years ago. Other works are dated even earlier. In fact this famous work was probably composed in the 4th or 5th century of our own era. About all we can say is that there is some evidence from ancient literature that in very early times India was cognizant of calculations, of astronomy, and of geometry.
