Biography
He was born on 1 November 1821, to a Hindu Brahmin family of Maharashtra. He received his early education in arithmetic and algebra at the Marathi school in Nagpur.

In 1842 Sastri went to Government Sanskrit College, Varanasi, where he taught rekha-ganita (Euclidean Geometry). In 1890 Sudhakar Dwivedi was appointed the teacher of mathematics and astrology after Bapudeva Sastri, retired in 1889.
