summand

English

Etymology

From sum + -and.

Noun

summand (plural summands)

1. Something which is added or summed.

   In the expression 1+2=3, the summands are 1 and 2.

Usage notes

One says that $x$ is a summand of $z$ if there exists some $y$ such that $x+y=z$ (where $x$, $y$, and $z$ are all understood to be objects of a certain type, such as numbers, vectors, etc., which the context makes clear). For instance, working over the positive integers, 3 is a summand of 5 (because 3 + 2 = 5), but 7 is not a summand of five.
