Scalar multiplication is a term used in linear algebra, which is the multiplication of a scalar (a real number) and a vector. This operation is also known by different names, making it easier for learners to grasp the concept by using different terms. One of the synonyms for scalar multiplication is the scaling of a vector, where scalar represents the scale factor that magnifies or reduces the size of the vector. Another synonym used for scalar multiplication is the scalar product of a vector, which emphasizes the inner product between the scalar and vector. Additionally, the term vector scaling also portrays the same concept as scalar multiplication. Thus, understanding these synonyms can help learners comprehend the concept more efficiently.
