Repeated Addition

$\cdot$

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 .
