Kertolaskuilla

Kertolaskuilla is a Finnish linguistic form derived from kertolasku, meaning multiplication. In Finnish grammar, the suffix -illa/-illä denotes instrumentality or context, and the ending is used to express “with” or “by means of” the base noun. Therefore kertolaskuilla literally means “with multiplications” or “by means of multiplications.” In everyday language and instructional texts, kertolasku refers to the arithmetic operation of multiplying numbers, while kertolaskuilla is used to describe activities or situations that involve performing multiplications, such as exercises, problems, or methods that rely on multiplication.

Common related terms include kertotaulu (the multiplication table), which lists products of integers, and kertolaskenta (multiplication calculation), the process of computing products. These terms are central in Finnish mathematics education, where multiplication basics are typically introduced in primary school and reinforced through practice and problem solving.

Kertolaskuilla is not a standalone mathematical concept; rather, it is a grammatical form used to talk about multiplication-related activities and contexts. Its usage is mainly found in instructional language and descriptive prose about mathematical tasks, rather than as a distinct theory or method.
