Aryabhatta's most notable work is the 'Aryabhatiya,' a comprehensive treatise that covers various topics in mathematics and astronomy. This work is divided into four sections: Gitikapada, which deals with time and mathematics; Ganita, which focuses on arithmetic and algebra; Kuttaka, which discusses the rules for solving equations; and Golapada, which addresses spherical astronomy. In 'Aryabhatiya,' he presents his findings in a concise and poetic format, making it accessible for scholars of his time. Another important work attributed to him is the 'Aryabhata Samhita,' which further elaborates on his astronomical theories. These texts have been studied and revered for centuries, forming a crucial part of the mathematical and astronomical literature in India.
