The Elements of Arithmetic

It is well known that Augustus De Morgan was a prolific and versatile man of science, who made important contributions in many branches of mathematics. In the Elements he concentrated on elementary arithmetic, presenting the subject clearly and systematically, avoiding all unnecessary detail. This book served as a foundation for modern textbooks on elementary algebra. De Morgan later supplemented it with an introduction to the study of logical symbols, which contained important ideas on these topics that were not published until after his death. This classic book is a must read for all mathematics students and anyone interested in the history of mathematics. The work is especially important for its insights on dimensional analysis and symbolic algebra.
