This is what I was looking for. Maxima is awesome. Thank you so much for the information.

Though it is not a general purpose math program, it is free and very useful for researchers in Group Theory and permutations:

Geogebra is another powerful website as well

I am looking for a PC equivalent of an iOS app that shows a line of consequtive numbers, where you can put a marker between them, and go into closer details, showing more and more decimals.

This is great for younger students that do not know how to round of decimals correctly yet.

Anyone know about such a program?

I use the three math software listed above for teaching Civil and Environmental Engineering courses. MAXIMA for symbolic calculations, SCILAB for numerical calculations, and R for statistical applications. In the last year and a half I’ve also been using SMath Studio, a paper-like application for mostly numerical calculations, but with some basic symbolic calculations. Here’s the website for the most current (although, still “beta”) version:

I’m not aware of an built-in, easy solution and you can’t use assume like that. See: http://www.math.utexas.edu/pipermail/maxima/2006/003702.html

hi,
In wxMaxima Linux, I try assume(x>0);solve( x^2-4)

but it gives x=-2 and x=+2 , but why doesn’t it respect the context and just give x=2?

Graphing Calculator 3D, as pointed out by Don, is a great alternative to the more complicated software such as Maple. When designing Graphing Calculator 3D we tried to focus on the most commonly used features, hence it is much easier and quicker to use. In addition, the 3D graphs produced by this 3D grapher are much nicer than those of other tools due to the extensive use of graphics card rendering hardware facilities which includes shading, light reflections and transparency.

I was after a good 3D graph program, having had no success with WolframAlpha. Some of the bigger programs you suggest gave me trouble in installing for various reasons (probably my fault). But I hit upon Graphing Calculator 3D which worked fine. You can even move your viewpoint to any direction by dragging with the mouse pointer. The free version does not allow you to save or print results, but you can use printscreen (on WindowsXP) and paste it into any program.

Python,as a language or anything else,is really a very good tool ,with a lot of open source package.So why not try Python.
