Thanks guys that almost worked. It installed the Wolfram engine but did not install the Mathematica part. The good news is I can still do math. I presume the problem is with the java that Mathematica seems to need on the Raspberry.
Anyway I ordered another sd card so I may just start over.
I'm having problems installing Mathematica. I used: 'sudo apt-get update && sudo apt-get install wolfram-engine' It seemed to work well. But the license screen come up with the little <ok> at the bottom. I could not click on it or find a way past it. I eventually had to close out of it. Reading othe...
