addition. That is, c(dv) = (cd)v and c(u + v) = cu + cv, and (c + d)v = cv + dv. Scalar Multiplicative Identity: There exists a scalar 1 such that 1v = v for any vector v in the space. A vector space can have various dimensions, including finite-dimensional spaces like Euclidean spaces (e.g., 2D or
