I am self-studying vectors. I have come across a different notation style. Usually, coordinates are written (x,y,z) but this alternative style is written as a column.
Furthermore, this vector column (A) is multiplied by another vector column (B) to obtain the cross product. But this multiplication doesn't make sense to me as it violates the rule that the number of columns of A should equal the number of rows of B in order to multiply 2 matrices.
Thank you.
