kertolaskuna

Kertolaskuna is a Finnish linguistic term used to refer to a multiplication calculation or problem, typically described or presented in educational or mathematical texts as belonging to the multiplication operation. In ordinary Finnish mathematics, the operation is usually called kertolasku, while kertolaskuna functions as a form that marks the content as being about multiplication, for example in descriptions or explanations.

Etymology and form: the term combines kerta, meaning “times” or “multiplicand,” with lasku, meaning “calculation” or “computation.” The suffix -na (or -nä) in Finnish often marks a manner or role, here indicating that something is presented or considered as a multiplication task.

Usage and context: kertolaskuna is most commonly found in language descriptions of how arithmetic is taught or explained. It is not a separate mathematical operation; rather, it signals that the statement or task is expressed as a multiplication calculation rather than an addition, subtraction, or division task. For example, a textbook might discuss a problem “kertolaskuna 3 ja 4,” meaning the problem is to be treated as a multiplication 3 × 4.

Relation to other terms: the core operation is kertolasku (multiplication). Kertolaskuna appears in linguistic or instructional contexts to describe the mode of presentation, rather than introducing a distinct mathematical concept.

Note: The term is primarily used within Finnish-language educational materials and linguistic discussions; in everyday math practice, the standard term for the operation remains kertolasku.
