WebbThe Simplex Method for Systems of Linear Inequalities Todd O. Moyer, Towson University Abstract: This article details the application of the Simplex Method for an Algebra 2 class. Students typically learn how to use the rref button on the graphing calculator. This leads the students to believe that every matrix can be row reduced in that manner.

WebbTwo examples are given (one is commented). Each of them consist of a cost vector, a matrix of restrictions and a right sides vector. Moreover, a basic matrix B containing the initial feasible solution and the indexes of that solution (relative to the matrix of restrictions) are also given. This initial solution is called a basic solution. WebbThe simplex method provides an algorithm which is based on the fundamental theorem of linear programming.
