Damn... thats a lot of code for a calculator... i just wrote this out in a minute and
it can workout anything Perl can evaluate including variables (though they require
my, remove use strict to get rid of that).
#!/usr/bin/perl -w
use strict;
#get the sum to evaluate
chomp(my $sum = <STDIN>);
#display it
print " = ";
eval "print $sum";
print "\n";

I see you've modified it. Much better!
Now how would you make i remember past sums such as the ability to do this kind of
thing:
1 + 2 = 3
+ 2 = 5
- 3 = 2
Kind regards,
Scott
