The video tutorial explains how to find the cross product of the difference and sum of two vectors, A and B, using two methods. The first method involves calculating the resultant vectors and setting up a 3x3 determinant to find the cross product. The second method uses properties of cross products, such as distributive properties, to simplify the calculation. Both methods yield the same result, demonstrating the consistency and reliability of vector algebra techniques.
