1. I don't get how to use AddRow. I think I remember that there was a
one-key way to add a row or column.
2. How do I change the color of comments?
3. How can I make Det[mfg] appear in expanded form like Det[mff] does?
mff = Array[Subscript[a, ##] &, {3, 3}];
mfg = MatrixForm[mff];
Det[mff]
Det[mfg]
I haven't used Mathematica for several years and am using it again.
Thanks for any tips.
