Concept Map

This concept map shows how the chapter fits together. Algebra here splits into three areas: Matrices (their order, types, algebra, transpose, symmetric/skew forms and inverse), Determinants (minors, cofactors, adjoint, area of a triangle and their properties), and using both to solve systems of linear equations (inverse method, Cramer's rule, row reduction, and the Leontief input-output model). Keep it in mind as a map of what you are about to learn.
