simple question - simple answer


The addition "+" is done in Mathematica via the function Plus, that has the
attribute Listable, which means you can incerement each elements in a list
like this:

{a,b,c,d,e} + 1

or Plus[{a,b,c,d,e},1]


See for yourself,

Attributes[Plus],

Attributes[Sin] ---} Sin[{0,1,2,10}]


Bye,

Borut
