Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. It's 100% free, no registration required.

I have finally decided to go more deep into math and cs, so to do that I will need proper tool, math tool. Could you please tell me what's the best open source math tool on the web today, since as far as I know majority of good math tools require you to pay for it, which is cool, but I am student and need some open source one and extra cash in my pocket. All are permitted to participate in choosing the best math tool.

Thanks in advance.

Specifying the type of math you plan on doing will help us give a more detailed response. –  Austin Mohr Apr 11 '12 at 20:54
    
I agree with Austin. If you want to do "applied math," involving numerical computation/analysis, something like octave might be good. If you want to do "pure math" a computer algebra system like GAP might be good. If you're not sure, I would recommend Sage which combines the best open source packages in one platform. –  William DeMeo Apr 11 '12 at 21:00
    
A link to Sage: sagemath.org –  Matthew Conroy Apr 11 '12 at 21:01
    
So it's Sage that you propose me to go with? And, yes I am not sure, basically all math involved would be best, if it's not possible then something more related to applied math would be OK too. –  Serenity Stack Holder Apr 11 '12 at 21:02

umm, octave is a good clone of mathcad, and its opensource, but really - mathematics, computer science are vast areas - need to be more specific - are you looking for software that is designed for educational purposes or software which aids in computation, problem solving etc. –  user996522 Apr 11 '12 at 21:02

If you are at uni and can show digital image proving your enrollment. You can use Matlab under a student license. Also for statistics in particular R is quite famous and free i believe. Other software options maybe Ocatve but i have n't used that one before.

Yes, I have R already installed here, but it's more for statistics, rather than math. Also, I am a bit too lazy for going Matlab license, and I am not sure whether or not my faculty has a contract with Matlab Corporation. –  Serenity Stack Holder Apr 11 '12 at 21:04
    
You do n't need your faculty to contact them . I think they way i did it was download and install matlab when you need to activate it send the matlab guys a screen dump of you logged into your uni website showing that you are enrolled and undertaking classes this year and they would send you the key in a day or so. I think Matlab is a great tool and definitely worth the the effort, the direct competition to it is open source scilab which lacks documentation and some functionality. I went the scilab way and then converted to matlab. Good luck –  Hardy Apr 11 '12 at 21:48

SCaVis computational environment is free program (under GNU public license). It is Java, so it runs even on Linux/Mac. I use it for free since I do not do complicated staff, but when you need to do something sophisticated, you need to setup a membership.
