in reply to Add Array values

You have to add them in a loop. However, there are ways to help you with that. If you wanted to do it by hand, you could say 
my $arr = [7,8,11];
$hash{one}[$_] += $arr->[$_] for 0 .. $#{$hash{one}};

But, that's ... ugly. A better way would be to use tye's Algorithm::Loops as so 
use Algorithm::Loops qw( MapCarE );

@{$hash{one}} = MapCarE { $_[0] + $_[1] } $hash{one}, [7,8,11];

The nice thing about this is that you can add more arrays to the end, update sub a little, and you're good. :-)

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
