This is the instructor's guide to a text designed for the contemporary business student who frequently questions the need for studying mathematics. The text material is presented in a "building-block" fashion, with skills learned in earlier chapters organized to provide a smooth transition into more difficult topics. This guide consists of sections which parallel the text organization. Each chapter opens with a short paragraph describing the nature and rationale of the corresponding portion of the student text. The bulk of each section in the instructor's guide deals with solutions and problem-solving methods for the exercises found in the student text. Topics covered are: (1) Review of Algebra, (2) Systems of Linear Equations, (3) Matrix Algebra, (4) Matrix Inversion and Applications, (5) Linear Programming-Graphing Concept, (6) Linear Programming, (7) Nonlinear Polynomial Functions, (8) Exponential and Logarithmic Functions, (9) Math of Investment and Finance, (10) Differential Calculus, (11) Differential Calculus Advanced Topics and Applications, (12) Multivariate Differential Calculus, (13) Integral Calculus, (14) Probability Theory, and (15) Probability Distributions.
