    Hi,

    When I was a student, I frequently used Mathematica and am accustomed to the notebook format in which I can easily define variables. Now that I am no longer a student, I no longer have a license to use Mathematica. Are there any free or inexpensive mathematical applications that let you define variables to do relatively simple calculations [I don't need something nearly as powerful as Mathematica for solving integrals or manipulating matrices] -- basically just a scientific calculator with a notebook and ability to define variables?

    By the way, I can use Mathematica on my husband's computer, and I'm struggling with the PrintPrecision function. It's set at 6 but for our taxes we need 7 digits, and I can't figure out a non-awkward way to fix the problem. Does anyone have any suggestions?

    thanks! :)

    I can't answer your first question, but as for PrintPrecision, you can change it in the global options in Preferences - just search for PrintPrecision (it is in Formatting options, Expression formatting, display options), and change it to 7. It is then retained for future Mathematica sessions.

    This would do it:

    I think the Mac version has the smae functions as the Windows, try it out anyway, it's free.
