(number.to_i + 1).to_s

You're trying to merge a String and a Fixnum into one object (i.e.,
you feed one big string obect to puts; you can't merge a Fixnum and
String like that).  The to_s method will convert the Fixnum you
created with to_i and added one to back to a string for output.

Kind of confusing I know, but if you got this far, I'm sure youll get it. :)
