Question 1: Is it possible to take the cross product of [1]x[1]

No, cross product requires 3D vectors (or 7D) Yes, the result is 1 Yes, the result is 0 No, cross product requires 2D vectors

Question 2: Is it possible to take the cross product of [1,2]x[1,2]

No, cross product requires 3D vectors (or 7D) No, cross product requires 1D vectors Yes, the result is 4 Yes, the result is 0

Question 3: Is it possible to take the cross product of [1,2,3] x [1,2,3]

No, cross product only works with 2D vectors Yes, and the result is [0,0,0] since the vectors are parallel No, cross product requires two different vectors Yes, and the result is [1,2,3]
