Hello, I'm trying to get the sum of the elements inside of my array. The elements inside of my array are 5 random numbers between 1 and 50. This is what I've got so far:

#!/usr/bin/perl
use strict;
use warnings;

my %num;

while ((keys %num) < 5) {

    $num{int(rand(50)+1)} = 1;
}

print join(' ' , keys %num) . "\n";

my @array = join(' ' , keys %num) . "\n";
my $sum = 0;

foreach my $var (@array) {
    $sum = $sum + $var;
}

print("The sum is: $sum\n");

This first gives me my 5 random numbers, then, the line below is supposed to say "The sum is: (my sum here)." I keep getting the following as an error, and only the first random number is displayed:

sh-4.2# perl
main.pl
16 30 21 7 11
Argument "16 30 21 7 11\n" isn't numeric in addition (+) at main.pl line 18.
The sum is: 16

Does anyone have any input on what I can do to make this work correctly? Thank you!!!
