Definition
Let $\struct {S, *_1, *_2, \ldots, *_n, \circ}_R$ be an $R$-algebraic structure with $n$ operations, where:
- $\struct {S, *_1, *_2, \ldots, *_n}$ is an algebraic structure with $n$ operations
- $\struct {R, +_R, \times_R}$ is the scalar ring of $\struct {S, *_1, *_2, \ldots, *_n, \circ}_R$.
The elements of the scalar ring $\struct {R, +_R, \times_R}$ are called scalars.
