In Spain, there's a famous website called Wiris that is a multi-platform website with the ability to create and calculate some of the most basic mathematical operations, but also you can save your project and continue after a while!

I was wondering if there is any other website or program similar to this, to create your own project with formulas and variables and, after only inputting the necessary data, the program calculates everything you want!

I was trying by creating autofilling sheets in Microsoft Word or LaTeX but they don't convince me (also in LaTeX I couldn't)

So, any suggestions?

  • $\begingroup$ @BenCrowell Exactly! That's why I was looking for other opcions :) $\endgroup$ – Meru Oct 8 '14 at 13:19

Having taken a quick look, what you are looking for seems to be a computer algebra system with a workbook, into which you can save your progress. The most well-known is of course Mathematica, but depending on what you want to do some people prefer MatLab or Maple. For a pretty big list you can consult the Wikipedia listing of CAS. Here I note a few free (as in beer, and sometimes as in speech) programs or websites.

  • GNU Octave is designed as a free software replacement for MatLab, and covers many similar functionality, and uses similar syntax.
  • Sage is a bundle of free mathematics softwares with a more-or-less unified interface. They have currently an online service that is in beta called SageMathCloud which seems to be very similar to Wiris in terms of functionality.
  • One can also make use of SymPy together with an IPython Notebook to reproduce somewhat the Wiris experience.
  • (A little bit of a shameless plug: I wrote some code sometime ago for helping with algebraic computations using IPython Notebook. There is no built-in CAS capabilities in my code; that is to say all math must be done in your brain. It is just a convenient replacement for paper and pen when I want to be more organized about writing things down.)
  • Maxima can be used with various frontends (I personally prefer wxMaxima) to get the similar experience of having a workbook which you can save.

  • $\begingroup$ A wonderful answer! Thank you a lot! I'll try out some of them to see what I can get :) $\endgroup$ – Meru Oct 7 '14 at 12:24
  • $\begingroup$ plus one for sage sagecell.sagemath.org plays nicely with python, latex, plots, etc $\endgroup$ – user1040 Oct 23 '14 at 8:06

this is Ramon from WIRIS team.

We are working on a Javascript version of WIRIS CAS. Still in beta. www.wiris.com/calc/
