title: Ruby gets/puts only for strings?
body: <p>I'm new to Ruby and am currently working on some practice code which looks like the following:</p>
  
  <pre><code>puts 'Hello there, Can you tell me your favourite number?'
  num = gets.chomp
  puts 'Your favourite number is ' + num + '?'
  puts 'Well its not bad but  ' + num * 10 + ' is literally 10 times better!'
  </code></pre>
  
  <p>This code however just puts ten copies of the num variable and doesn't actually multiply the number so I assume I need to make the 'num' variable an integer?  I've had no success with this so can anyone show me where I'm going wrong please?</p>
