A fast, simple and error free method of solving LP on calculator.
Linear Programming is a fundamental tool in optimization. Most of the texts discuss how to solve this using row manipulations in simplex tableau. This method is fundamental but gets messy with bigger problems. Computer can solve large LP problems as they convert it to a matrix form. Such methods are fast and efficient.
Here we learn how to use this efficient method and solve the LP on a calculator. Modern calculators are capable of matrix algebra. Solving LP problem is now a breeze with this. The method discussed here is the precursor to understanding how computers solve LP, and mimic this on calculator.
