I am very new to ruby and I was hoping someone could help me. In the following script I am asking the user their favorite number. I would then like to add a one to their favorite number and suggest the resultant number as a better favorite number.

puts 'What\'s your favorite number?'
number = gets.chomp.to_s
puts 'Your favorite number is '+number+'.'

If anyone could tell me how to this it would be great!

puts 'What\'s your favorite number?'
number = gets.chomp.to_s

new_number = number.to_i + 1

puts 'Your favorite number is '+new_number+'.'

To explain a little bit more:

new_number = number.to_i + 1

Converts 'number' which you converted to a string before with 'gets.chomp.to_s' (you read the input from the terminal and converted it to a string so it can be appended to the other string that you are printing out with the other 'puts' statement. Fine.

However, a short way to do all that is also:

number = gets.chomp.to_i + 1
puts ' A better number is ' + number.to_s
