A series is said to converge
absolutely if the series
converges,
where
denotes the absolute value. If a series
is absolutely convergent, then the sum is independent of the order in which terms
are summed. Furthermore, if the series is multiplied by
another absolutely convergent series, the product series will also converge absolutely.
