thank you sir....thanks very much

I really learned a lot about vectors

With cross products you subtracted j part but added the k part. Why?

It is because of finding the cofactor of the minors of the matrix. Look further into that and it'll give clarity.

Very bad that you didn't explain why you subtracted j, while added k !!
