Vollständige Anleitung zur Niedern und Höhern Algebra

This three-volume German edition of the groundbreaking 1770 algebra textbook by the Swiss-born mathematician Leonard Euler (1707–1783) draws heavily upon additional material by Joseph-Louis Lagrange that appeared in an early French translation. Volume 3 contains Lagrange's additions, translated into German, and six appendices by the translator.

In 1770, one of the founders of pure mathematics, the Swiss-born mathematician Leonard Euler (1707–1783), published an algebra textbook for students. It was soon translated into French, with notes and additions by Joseph-Louis Lagrange, another giant of eighteenth-century mathematics, and the French edition was used as the basis of this three-volume 1790s German edition. Volume 3 consists of the German translation of Lagrange's additional material, which the German publisher printed in a separate volume to enable those who already owned Euler's Algebra to obtain the supplementary material 'without incurring unnecessary expenditure'. The translator (the tutor to the sons of the Duke of Württemberg) added notes and further appendices of his own. This book provides tangible evidence of the lively international mathematical community that flourished despite the political uncertainties of the late eighteenth century.
