Subject: Re: Pine's book "Learning to Program" - Answer?

1.) if you do a .to_i to num, you dont need to chomp it.
2.) if you make 'num'.to_i you try to transform the string num into 
integer. it should be num.to_i, because you want the value of num and 
not "num".
3.) #{expression} in string will be replaced with its value in that string.
try

(1..10).each do |number|
   puts "Hallo there, Number #{number}!"
end

hope that helped ;)

sorry about my english, i know it sucks alot!
