Summa de arithmetica, geometria, proportioni et proportionalita

This book, written by Luca Pacioli, is a seminal work in mathematics and accounting.

It includes a general treatise on theoretical and practical arithmetic, the elements of algebra, a table of moneys, weights and measures, and a detailed description of double-entry bookkeeping.

The book also covers practical geometry and was the first printed work on algebra.

It played a significant role in standardizing professional accounting methods and influenced later mathematicians such as Cardano and Tartaglia.
