Do I need to store the random integers in variables or something.?

Yes, but you are already doing that. Here's one approach with a subroutine and using an array to hold the operands.

#!/usr/bin/env perl use strict; use warnings; while (1) { my @operands = (int(rand(100)), int(rand(100))); ask ($operands[0] > $operands[1], @operands); } sub ask { my ($subtract, @args) = @_; my $input; my $answer = $subtract ? $args[0] - $args[1] : $args[0] + $args[1] +; my $oper = $subtract ? '-' : '+'; until (defined $input && $input == $answer) { print "Nope, try again\n" if defined $input; print "What is $args[0] $oper $args[1] ? "; chomp( $input = <STDIN> ); }; print "Success!\n"; }

Edit: sigil fix on the ask() call.
