I need to multiply a variable that contains a negative value by negative one.  Such as $test=(-1*$amount) where amount is negative.  I can't even get print "Test (-1*$amount)"; to work.  This prints: -1*-300.

Either do

$test = -1 * $amount;
print "$test\n";

or

print -1 * $amount , "\n':

 $test=(-1*$amount) ;
should work.
so would
  $test = -$amount;

  print "Test (-1*$amount)";
will just print the "Test (-1*" litterally
perhaps you meant
  print "Test", -1*$amount,"\n";
