You have to be in the CAS environment for that.

Thanks a lot! The input and the solving for m2 worked perfect. This must have been easy. But, where did you get the yellow Shift "U" in the upper left corner, to obtain the ANS(....)?

That indicates a locked User keyboard; press User ("Shift Help") twice. Pressing it once (1U) will activate the User keyboard for the next keypress. Pressing it twice (^U) will keep it activated.

But Ans is "Shift +".

Solving the equation for m2 works now. Thank you very much! But how do I get the values into the list and a solution for them?

It does not work with "Shift Ans", bracket, Variable=.., .., Enter

It really great to get help here - Thanks a lot.
