Khulāṣat-ul Rāz or Khulasah-i-Raz ("Essence of Mystery [of Arithmetic]") is a book on arithmetic, algebra and mensuration. It is an abridged translation of Baha' al-din al-'Amili's Arabic language book Khulasat al-Hisab, which was used as a textbook in madrasas of medieval India. The author wrote the book in verse form, and dedicated it to the Mughal prince Dara Shikoh.
