Hundreds of completely solved problems throughout
Trade Review
"Standard material is covered here such as basis, linear transformations, the general linear group, systems of linear equations, determinants and eigenvalues. The book has many examples and exercises to help the reader." (Zentralblatt MATH, 2016)
"The author goes deep enough into group theory to cover normal subgroups and isomorphism theorems, and deep enough into linear algebra to discuss eigenvalue theory and the general linear group. There are plenty of exercises and supplementary problems... the book is certainly different from the competition." (Mathematical Association of America, 2016)
