"The cross-product of Z scores the result of multiplying a person’s Zscore on one variable by the person’s Zscore on another variable."

"In mathematics, the cross product, vector product, or Gibbs' vector product is a binary operation on two vectors in three-dimensional space. It results in a vector which is perpendicular to both of the vectors being multiplied and therefore normal to the plane containing them. It has many applications in mathematics, physics, and engineering. "

"The cross product a × b is defined as a vector c that is perpendicular to both a and b, with a direction given by the right-hand rule and a magnitude equal to the area of the parallelogram that the vectors span. "

In 1991, India adopted liberal and free-market oriented principles and liberalized its economy to international trade under the guidance of Manmohan Singh, who then was the Finance Minister of India under the leadership of P.V. Narasimha Rao the then Prime Minister who eliminated License Raj a pre- and post-British Era mechanism of strict government control on setting up new industry. Following these strong economic reforms, and a strong focus on developing national infrastructure such as the Golden Quadrilateral project by Atal Bihari Vajpayee, the then Prime Minister, the country's economic growth progressed at a rapid pace with very high rates of growth and large increases in the incomes of people.

"The cross product, also called the vector product, is an operation on two vectors. The cross product of two vectors produces a third vector which is perpendicular to the plane in which the first two lie. That is, for the cross of two vectors, A and B, we place A and B so that their tails are at a common point. Then, their cross product, A x B, gives a third vector, say C, whose tail is also at the same point as those of A and B. The vector C points in a direction perpendicular (or normal) to both A and B. The direction of C depends on the Right Hand Rule. "

"To emphasize the fact that the result of a dot product is a scalar, while the result of a cross product is a vector, Gibbs also introduced the alternative names scalar product and vector product for the two operations. These alternative names are still widely used in the literature. "
