I'm fairly confident on A X B since I checked it with my notes from class.

However, for the triple scalar product, in our notes we started with b-sub j and c-sub k. I started with b-sub i and c-sub j, so the order of my indices were different. I also worked out the operations separately then combined them at the end. In class, we wrote everything out all at once. I get the feeling that's the better way to do it. Thanks for any help.
