The study topics begin with definitions and vocabulary related to the study of matrices. Addition/subtraction of matrices, scalar multiplication and multiplication of matrices are introduced and practiced. Next a section of problem solving investigates uses and applications of matrices. The next topics are determinants, inverse matrices (and their uses in solving systems), expanding by minors, properties of determinants, and the famous uses of Cramer's Rule. Each section offers plenty of practice with detailed solutions followed by a test of the material studied. Available for immediate download.
