(9 Sept 00) (305K) is for high-precision geometric constructions in both two and three dimensions. Drawings can be highlighted and animated in a variety of ways. (22 Sept 00) (236K) is a general-purpose plotting utility, which can draw (and animate) curves and surfaces presented in a variety of formats. (29 Sept 00) (247K) provides access to scatter plots, curve fitting, histograms, statistical data, and standard theoretical probability distributions. It also simulates dealing cards, sampling candy, tossing darts, needles and coins. There are two least-squares demos and a curve-fitting demo. (9 Sept 00) (138K) is a collection of subprograms that deal with discrete-math topics such as apportionment, voting power, voting methods, and network analysis (traveling salesman problem, map-coloring,...). (9 Sept 00) (171K) is a fractal exploration program. It allows the user to explore functional iteration, including Mandelbrot and Julia sets, ferns and snowflakes, web and bifurcation diagrams, and more. (9 Sept 00) (186K) currently includes eight subprograms: conic sections, star polygons, three-body simulator, a root-finding utility for elementary functions, a 2-dim mapping visualization, roulettes, random functional graphs for students to ide (9 Sept 00) (149K) is a collection of game subprograms, currently including Life, Krypto, Boxes, Hex, Rubik, Mazes, Pegs, Bishops, the Loyd 15 puzzle, and Spaceship. (9 Sept 00) (127K) allows the user to calculate and edit matrices, and solve standard linear algebra problems. (9 Sept 00) (78K) is a high-precision integer calculator, for numbers with thousands of digits. Old DOS versions of the above Windows programs. Mathematical documents in PDF format.

Listed to the side are abstracts and links for downloading free mathematics software. Hold the mouse over each for a date and a short description.

The programs may be freely distributed, and the author (rparris@exeter.edu) welcomes suggestions for improvements and repairs. Current versions (dated with the program) are always available at this site (Phillips Exeter Academy).

Each program link will supply you with a self-extracting archive. This file contains the executable file and perhaps some accessory files. The executable file also includes documentation that can be printed, exported to your word processor (as was done below with the documentation for Wingeom), or simply used for on-screen help.

To download programs, first create a directory on your hard drive into which the files will be copied. Then click the desired links. After downloading, execute each file ("run" it) to extract its contents. You will have to register the programs with the Windows Program Manager yourself.

You can return to this page by clicking any of the peanuts you come across on the web site.
