Definition:Right Cancellable Operation

Definition
Let $\struct {S, \circ}$ be an algebraic structure.

The operation $\circ$ in $\struct {S, \circ}$ is right cancellable :
 * $\forall a, b, c \in S: a \circ c = b \circ c \implies a = b$

That is, all elements of $\struct {S, \circ}$ are right cancellable.
