$\cdot$

Often used to denote the power of the additive binary operation in a general ring $\struct {R, +, \circ}$.

In this context, $n \cdot a$ means $\underbrace {a + a + \ldots + a}_{n \text{ times}}$.

See Powers of Ring Elements‎ for an example of how this can be used.

Also often used for the binary operation in a general group which is not necessarily abelian.

The $\LaTeX$ code for $\cdot$ is \cdot .
