Hello,

Newbie question here:

I have written a simple code to test my ruby knowledge. It is as  
follows:

* * *

class Mastermind

def k(a,b)  
v = a+b  
put v  
end

k(2,3)

end

* * *

When I run the class, I want to see the code return the number 5.  
However, when I run the code i get an error saying that the method K is  
undefined. What is wrong here?
