When you do computations on your ti-89, you can scroll up to see your past calculations.

When you do a calculation on the Wolfram Alpha website, and you X out the window, you can't go find it again.

To deal with this, I've been pasting URLs + a screenshot of what I typed in into a Word doc but I'd like to find software that can save this in a more elegant and automatic way to do this to save your past calculations. The other way I thought of doing it is shoving all the URLs into the bookmarks bar but that is a bit messy and hard to navigate.

At the moment, I'm only considering the Wolfram Alpha website since it seemed to handle words and English a bit better than other calculators I've used. I'm not going to use Mathematica because I don't feel like installing it on all my devices - there should be a simpler solution for what I want which is basically saving Wolfram Alpha searches in an easy to navigate way

What is some good software to keep a record of calculations in case you want to go back and check if you made a mistake?

  • Windows 10
  • Preferably free

I've tried the extension Save to Pocket, but if you try to open a pocket from the chrome extension app, it may say that Wolfram Alpha needs java even though you already have it and can use wolfram alpha just fine on a browser.

This may not be the answer that you are looking for but you can use python but the Wolfram Alpha library to query Wolfram Alpha in a repeatable manner and to save the results. If you use an iPython console you can save an interactive session to a python file that you can edit/reuse and if you use a Jupyter notebook you can do all of this from within a browser window and save both query & results into a Jupyter notebook along with images, markdown text, etc. You can also export both the code and results to a number of shareable output formats including pdf.

  • Price: All of the software mentioned above is $0.00 being gratis & open source
  • Platform: All of the above is available for Windows, OS-X, Linux & more
  • Installation: Quick and easy with an internet connection:

    1. Download and install python for your platform if Windows, (it is already installed on OS-X and most Linux distributions).
    2. For Wolfram Alpha library: At the Windows command prompt pip install wolframalpha to get and install the library and all of its dependencies, OS-X & Linux users should use the terminal and may need to prefix with sudo.
    3. For ipython: At the command line pip install ipython to get and install the library and all of its dependencies, OS-X & Linux users should use the terminal and may need to prefix with sudo.
    4. For Jupyter: At the command line pip install jupyter to get and install the library and all of its dependencies, OS-X & Linux users should use the terminal and may need to prefix with sudo.

You will need to get a developer API App ID from Wolfram Alpha - it is free for personal/experimental use.

One especially nice thing about this approach apart from reputability is that it is not limited to Wolfram Alpha but can be used, with different APIs, for many other potential data sources.

  • I'll try that out later but honestly there must be something that can just save the current URLs and make it syncable across computers. I've tried a few chrome extensions to save the tabs but it doesn't sync across computers – LongApple Oct 1 '16 at 3:28
