kwadratem

Kwadratem is the instrumental singular form of the Polish noun kwadrat, meaning square. It designates either a square as a geometric shape or, in grammatical contexts, the instrumental form used with verbs and prepositions that require the instrumental case. In mathematics, the square of a number is usually described by phrases such as „kwadrat liczby x” or „x do kwadratu,” and the exponent notation x^2 is commonly used.

In geometry, kwadrat also refers to a regular quadrilateral with four equal sides and four right angles; its area is the square of its side length, written as a^2, and described as „Pole kwadratu o boku a.”

Etymology: The noun kwadrat comes from German Quadrat, likely via the French carré; kwadratem is simply the instrumental case form.
