This book is designed to help students understand and solve
the four central problems of linear algebra that involve: (1) linear
systems, (2) least squares, (3) eigenvalues, and (4) singular
values.

The diagram on the front cover shows the four fundamental subspaces
for the matrix A. Those subspaces lead to the Fundamental Theorem of
Linear Algebra: (1) The dimensions of the four subspaces, (2) The
orthogonality of the two pairs, and (3) The best bases for all four
subspaces.
