Summattavat

Summattavat is a Finnish term used in mathematics and data processing to describe elements that can be included in a summation. It is the plural form of the adjective summattava, which is formed from the verb summata (to sum) with the -ttava suffix indicating capability or potential. Phrases such as summattavat luvut or summattavat termit refer to the items that may be added together.

Usage and context vary slightly by field. In finite contexts, the concept is straightforward: a finite collection has a definite sum when its summattavat elements are added. In the context of infinite series, discussions typically focus on the behavior of the sum formed from the summattavat termit, including questions of convergence or absolute convergence. Finnish texts often treat summattavuus (the property of being summable) as a related notion, especially when discussing conditions under which a series converges.

In addition to mathematical writing, summattavat can appear in data processing and programming discussions where values are intended to be aggregated by a sum operation. There, the term helps distinguish between values that will be included in a total and those that will not.
