Try this code: puts (2+4).to_s + ' is the sum of 2+4.' and puts 'Hello, what is your favorite number?' number = gets.chomp better = number.to_i+1 puts number.to_s + '?? Don\t you know that ' + better.to_s + 'is a superior selection?' But the right way to do this is to use expression inlining, such as there: puts "#{2+4} is the sum of 2+4." or puts "#{number}?? Don\t you know that #{better} is a superior selection?" It does .to_s implicitly. Notice the double quotes, it won't work with single. WBR, Peter Zotov
