WebMay 5, 2016 · •= (rx1, rx2) by the definition of scalar multiplication. •Being closed under scalar multiplication means that vectors in a vector space, when multiplied by a scalar (any real number), it still belongs to the same vector space. Webover K under the addition and scalar multiplication of V. Theorem Suppose that S is a nonempty subset of V, a vector space over K. The following are equivalent: 1. S is a subspace of V. 2. S is closed under vector addition and scalar multiplication. 3. S is closed under the process of taking linear combinations, i.e., if v and w are in S and " the circle maker kindle
