In Mathematics 12, Chapter 10, we studied vector addition and subtraction. Another algebraic operation that we intend to discuss in relation to vectors is their product. Let us remember that the product of two numbers is a number, the product of two matrices is again a matrix. But in the case of functions, we can multiply them in two ways, namely the multiplication of two functions and the structure of two functions. Similarly, the Multiplication of two vectors is also defined in two ways, namely, the scalar product (or point) where the result is a scalar, and the vector (or cross) product where the result is a vector. Based on these two types of vector products, they have found various applications in geometry, mechanics, and engineering.

Previously, we have discussed the right-hand three-dimensional rectangular coordinate system. In this system, when the positive x-axis is twisted counterclockwise towards the positive y-axis, a clockwise (standard) screw will move in the direction of the positive z-axis. In the right-handed coordinated system, the right-hand thumb points in the direction of the positive z-axis when the fingers curl away from the positive x-axis in the direction toward the positive y-axis.

The word vector is derived from the Latin word vectus, meaning “carrying.” Germ ideas of modern vector theory date from around 1800 when Caspar Vessel (1745–1818) and Jean Robert Argund (1768–1822) described how a complex number a + ib could be given a geometric interpretation with the help of a directed line section in a coordinate plane. William Rowen Hamilton (1805–1865), an Irish mathematician, was the first to use the term vector for a directed line segment in his book Lectures on Quaternions (1853).
