odjemna

Odjemna is a term used in Polish arithmetic to denote the minuend in a subtraction operation. It refers to the number from which another number is subtracted to obtain the difference.

In a subtraction expression written as a − b = c, the odjemna is a, the odjemnik is b, and the resulting value c is the różnica.

Etymology: the word derives from the verb odjąć "to subtract" and the suffix -na, forming a feminine noun that names the operand being diminished.

Usage: Odjemna is standard terminology in Polish math education and textbooks; it is contrasted with odjemnik, the subtrahend. The concept is central to basic arithmetic, place value, and number sense.

For example, in 9 − 4 = 5, 9 is the odjemna, 4 is the odjemnik, and 5 is the różnica.
