You're close.

better is a fixnum (like the error says).  In order to add it to the string=
,
you'll need to convert it to a string.  Luckily, ruby gives you a nice and
easy way to do it:

better.to_s will return the string version of better.

So, this makes the last line:

puts ' This is better: ' + better.to_s + '.'

Give that a shot.
