Welcome to this Treasure Chest of Free Stuff.

Here’s another sophisticated and attractive graphic calculator with the potential to serve elementary students and engineers alike. Jos de Jong, the program’s author, is offering the program free of charge, but he’ll welcome a $10 donation if you find the program useful. This will help with productivity in math, but I’ve filed under Content & Curriculum.

SpeQMathematics (downloadable program and online resource) Whether you need to do basic computation or advanced math on the computer, this resource may be your answer. You can either download the complete powerful program to your Windows PC, or you can go to the website and do basic work online. Although the user interface is simple and intuitive, the greatest potential by far is for those who need a tool to complete advanced math problems involving mathematical or scientific notation.

Since I’m no mathematician, and my descriptions and explanations of the program will fall short, click on the image below for a clearer (and enlarged) idea of at least some of the potential.

Online tutorials are available. At less than half a megabyte, SpeQ is a very small download; and it will run on virtually any Windows machine–all the way back to Windows 95.
