This in-depth introduction to classical topics in higher algebra provides rigorous, detailed proofs for its explorations of some of mathematics' most significant concepts, including matrices, invariants, and groups. All topics are developed with a remarkable lucidity and discussed in close connection with their most frequent mathematical applications. 1926 edition. Unabridged republication of Modern Algebraic Theories, published by Benj. H. Sanborn & Co., Chicago, Illinois, 1926.
