Is there a proper English term for Z in this example?

a = [ 1, 2, 4 ]

b = [ 1, 1, 1 ]

Z = [ 2, 3, 5 ]

    I'd assume "set sum" would be a sufficient term to describe Z.2011-05-18

    @Neil: that's a fairly confusing term. What is "set" describing?2011-05-18

    what you describe are not sets. In mathematical parlance, sets have distinct elements.2011-05-18

    Also generally sets are not ordered. I would call them sequences, then Z is the sum of sequences a and b.2011-05-18

    Or vectors? Sum of vectors?2011-05-18

You can say that $Z$ is the "pointwise sum of $a$ and $b$" or "coordinate-wise sum".

This can be seen as addition in a three dimensional vector space (or free module).
