Casio Prizm programs for all versions of the calculator. Some programs designed for earlier versions (the CG10 and CG20) may not work correctly on newer calculators (the CG50). We have a guide for how to put programs on the calculator. Lua programs also need LuaZM to run.



  1. This is a port of the powerful Eigenmath math engine, by George Weigt, to the Casio Prizm, providing numerous math functions not originally available in these calculators, including symbolic computation. This port includes a function catalog, ability to create and execute scripts, draw graphs, and much more. All 100+ Eigenmath commands work. Output is pretty-printed whenever possible, and 200 lines of output are stored for scrolling at any time. Command execution can be stopped. The state of the add-in is optionally automatically saved when exiting. Source code and more info is available at: .
    This add-in will surely become an indispensable part of your calculator.

  2. Graph3DP is a powerful 3D graphing application for the Casio Prizm (fx-CG10/fx-CG20/fx-CG50). Enter one to six 3D equations, and rotate and zoom the resulting graph. You can adjust the window and trace over the mesh to examine X, Y, and Z value. This final 1.0 release has been thoroughly tested, and the underlying equation-parsing system, AHelper's gCAS2, has been overhauled for speed and correctness. Graph3DP understands thirteen built-in math functions, from sin() to atan() to sqrt() to ln(), plus addition, subtract, multiplication, division, grouping, and exponentiation. Give it a download and try it today; this will surely become an permanent fixture on your Casio Prizm.

  5. Updated file of Discriminant

    This program finds the discriminant of a 2nd degree trinomial,
    does the quadratic formula,
    and solves for k in direct, inverse, and joint variation,

    Soon to come:
    Right now I'm working on turning this into an Add-in. So the next version will (hopefully) be in Add-in form.

  7. Complete matrix calculation for Graph 25+Pro and FX-7400GII:

    Invert (INVERSE)
    Raise to higher power (M HOCH X)
    Multiplication with scalar (M MAL X)
    Multiplication with matrix (M MAL M)
    Determinant (REFDET)
    Gaussian elimination (REFDET)
    Gauss–Jordan elimination (RREF)

    Copy matrix to other lists (KOPIEREN)
    Generate a random matrix (M ERZEUG)

    Input of matrices in then lists of the STAT-application, calculation in PRGM-application, result again in STAT-application.

  8. ~MATH~ is just a simple program I made for the Casio fx-CG50 by combining all of the many math programs I'd already made to speed up the homework process. I basically made a program for everything I could when we learned it, so some of the functions in here will seem really random. Also, I'm only in Algebra 2, so don't expect anything mind-blowing. Also, I put a password on the program so that breaking (AC/ON) to exit wouldn't bring you to the source code. If you would like to view the source code, the password is "MATH"
