I don't know how to get the ^-sign into Mathemetica. Normally i just press Shift+^ and then "space" to get "^". It works when writing this message and also in the command line version of Mathematica, but not in the graphical version. I'm a complete beginner, I have googled on "Mathematica raspberry pi can't type ^" and similar things without success. I use a Swedish keyboard with "^" and "~" on the same key. Any Ideas?
