Might I recommend that you read a book about Ruby and/ or programming (I 
think Ruby).  In either case, reading Chris Pine's "How to Program" will 
give you all that you need to know about walking - and I think you'll be 
able to run after that.

Things like to_i and to_s, etc.  are quite elementary to any language 
and are covered in detail in books about the language.

Cheers,
Mohit.
