A classical theorem by Block and Levin (Block, H. D., S. A. Levin. 1970. On the boundedness of an iterative procedure for solving a system of linear inequalities. Proc. Amer. Math. Soc. 26 229-235) ...

Inequalities are the relationships between two expressions which are not equal to one another. The symbols used for inequalities are <, >, ≤, ≥. \(7 \textgreater x\) reads as '7 is greater than \(x\)' ...

“Mathematics is the art of reducing any problem to linear algebra.” This is a quote often attributed to William Stein, a former mathematics professor at the University of Washington, now the lead ...

Plotting graphs of inequalities works almost exactly the same way as plotting graphs. Simple inequality graphs can be plotted parallel to the \(x\) or \(y\) axes and tables of values can help to plot ...
