Hey Karthikeyan,

I just had a look at your book, it's great and will help people new to Ruby.

However, the book is interspersed with a lot of mistakes, most of them being grammatical. I'm sure that the community, including myself will help you fix them.

One thing I positively hate is the last section, "An important Math Discovery". The proof is mathematically invalid. You can not take (1-1/1-1) equal to 1, it is mathematically undefined (an indeterminate form). I strongly believe that the aforementioned section should be omitted.

Cheers,  
Umang.
