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.
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.
