Lectures on Elementary Mathematics

Lectures on Elementary Mathematics by Lagrange J. L. (Joseph Louis) delves into the foundational aspects of mathematics particularly focusing on logarithms and equations of varying degrees. Lagrange explores the significance of logarithmic tables in simplifying complex calculations tracing the evolution of logarithms from Napier to Briggs and Viacq. The book also discusses historical methods of solving equations including the use of imaginary quantities and geometric solutions. Through a comprehensive analysis Lagrange presents a new perspective on solving higher-degree equations highlighting the intersection of algebra and geometry.
