In this section systems of inequalities and linear programming are introduced.

In the first lesson graphing inequalities and systems of inequalites are shown. Terms like feasible region and terms related to it—corners, bounded, unbounded— are defined.

The last two lessons revolve around linear programming problems and how to solve them either graphically or by the simplex method. A conceptual overview of what the simplex method is and an online simplex solver are shown.
