Elements of Algebra is an elementary mathematics textbook written by mathematician Leonhard Euler around 1765 in German.
It was first published in Russian as "Universal Arithmetic" (Универсальная арифметика), two volumes appearing in 1768-9[1] and in 1770 was printed from the original text.
In 1771, Joseph-Louis Lagrange published an addendum titled Additions to Euler's Elements of Algebra, which featured a number of important mathematical results.
On the 300th birth anniversary of Euler in 2007, mathematician Christopher Sangwin working with Tarquin Publications published a digitized copy based on Hewlett's translation of the first four sections (or Part I) of the book.
[4] In 2015, Scott Hecht published both print and Kindle versions of Elements of Algebra (ISBN 978-1508901181) with Euler's Part I (Containing the Analysis of Determinate Quantities), Part II (Containing the Analysis of Indeterminate Quantities), Lagrange's Additions, and footnotes by Johann Bernoulli and others.
