This book, which deals with various branches of mathematics: trigonometry, geometry, algebra and more, was published based on the original manuscript of the Gaon of Vilna, as stated on the title page. A commentary by the editor R. Shmuel, rabbi of Luknik (Luokė), was printed alongside the composition of the Gaon of Vilna, since "due to the tremendous brilliance of the Gaon of Vilna, he was concise where elaboration is necessary for our level of understanding, and his words are only understandable after intense study…".
The book opens with a lengthy foreword by the editor R. Shmuel Luknik, followed by a second lengthy foreword by R. Yaakov Moshe of Slonim, descendant of the Gaon of Vilna. In his foreword, R. Yaakov Moshe relates at length to the correct way of viewing secular sciences.
R. Yaakov Moshe of Slonim also wrote an approbation to this book, in which he writes that R. Shmuel of Luknik was in possession of an "old copying" of this composition, and that he gave R. Shmuel the original manuscript of the Gaon to correct the text.
