Hi Monks,

I've spent the last 2 hours on this one. I hope someone can help me. I believe I am close. I need a program that will add or multiply any number of values and print out result. The problem I'm having is with the "any number of values part." I'm ashamed to admit it, but yes this is homework. 
# Program that will add or multiply as many numbers that are entered.
# Use the program as such: program.pl add 3 2 1

use warnings;
use strict;

my $rtn;

my $len = @ARGV;  #Get the number of elements
$len = $len - 1;


if ($ARGV[0] =~ /add/) {
 $rtn = add($ARGV[1]..$ARGV[$len]);
 print "The sum is: $rtn";
}
elsif ($ARGV[0] =~ /multiply/) {
 $rtn = multiply($ARGV[1]..$ARGV[$len]);
 print "The product is $rtn";
}


sub add {
 my $sum = 0;
 my @data = @_;
 for (@data){
  $sum += $_;
 }
 return $sum;
}


sub multiply {
  my $product = 1;
  my @data = @_;
  for (@data) {
   $product *= $_;
  }
  return $product;
}

Thanks.
