Looks like a few other folks have already solved your problem, so a
quick note on Ruby idiom/features. Ruby lets you use single *or*
double quotes to represent a string. The difference is that double
quotes allow variables to easily be inserted in your string. Also,
they make it easy to have apostrophes in your strings! A slightly
modified example, with no more \' pain:

puts "Hey there, I'm Uno."
puts "What's your favorite number?

number = gets.chomp
better = number.to_i + 1

puts "#{better}... That's better."
