Theorem

Let $\struct {R, +, \times}$ be a ring.


Then $\struct {R, +, \times}$ is a right module over $\struct {R, +, \times}$.

Proof

From Ring is Ideal of Itself, $R$ is a right ideal.

From Right Ideal is Right Module over Ring, $\struct {R, +, \times}$ is a right module over $\struct {R, +, \times}$.

$\blacksquare$
