When we have a bunch of numbers multiplied together like $$b=a_1\,a_2\,a_3\,a_4,$$ we say that each $a_i$ is a factor of $b$.
What is the additive analogue of this terminology? That is, if $$b=a_1+a_2+a_3+a_4,$$ how is $a_i$ called?

5Those are summands – Hagen von Eitzen Feb 26 '16 at 13:16

1They are also called terms. – Tim Raczkowski Feb 26 '16 at 13:17

"Summands", as in a previous comment, or "terms". – Ethan Bolker Feb 26 '16 at 13:18

2"Summand" is better; "term" can also be an element of a sequence. – TonyK Feb 26 '16 at 13:19

See also augend, addend. – Karl Feb 26 '16 at 13:25

"addend" (also). – BrianO Feb 26 '16 at 13:58

You can say that $a_i$ belongs to one of the partitions of $b$, and to one of the compositions of $b$. – barak manos Feb 26 '16 at 14:03

The additive analogue for multiplicative factors is summand.
An augend + addend = sum / total
Also summand + summand = sum
The equivalent of factorization could be called as summandization
