When I try to define variables in Mathematica they will not assign themselves, (a=, b=, etc.). The variable stays blue, even after I press enter. Can someone help?
I am using the Raspberry Pi 2 which comes with Mathematica. I do not know which version.
I tried resetting the kernel but it did not seem to have an effect. As the release that comes with the "Pi" is a beta release are there updates that I could be missing and where would I go to download those updates?
Have you tried restarting the Kernel (or even the entire session)? I have experienced similar (although very infrequently) on Mathematica 7 (os 10.4) when I hanged the system and the kernel quit. As a last resort try to reset Mathematica to its factory settings.
