Simplex using Casio calculator.

A linear simplex calculation using the matrix manipulation facilities of a Casio fx-CG50 calculator.
There are many arithmetic calculations required by the simplex algorithm, so the possibility of making a mistake is high. Many modern graphical calculators have matrix manipulation facilities that can be used to help minimise these possibilities.
The Casio fx-CG50 calculator is used here, but there are other calculators that could also be used.

This is excellent. Not just the clearest guide to using the Casio FX CG50 for the Simplex Algorithm, but also the clearest guide to the Simplex Algorithm. Thank you, Sir!

I'm not sure if this channel is still active, but I just wanted to say thank you! Only one in my college class with a Casio, can be super frustrating at times

What a great guide!

[@muratsumi]

Thank you soo much !! I used this guide to the casio fx-9750 GII

Unfortunately, no! 4 columns won’t even deal with two parameters very well.

Unfortunately the fx-991ex can't have row, column more than 4. You have any trick in that case?

[@stephenfroggatt8352]

Set Matrix A (3x3) to be the row operations multiplier. Set Matrix B (3x3) to be the first three columns. Set Matrix C (3x4) to be the last four columns. Multiply A by B for the first three columns of the next tableau then A by C for the final four columns. You could also use the spreadsheet mode, although there are similar restrictions, if you are not comfortable writing row operations as a matrix multiplier.
