Spencer,

@@number and @@number2 are class variables.  number and number2 are local variables.  Also, Ruby is case sensitive, so the doThis method and the dothis method are actually 2 different methods.

class Calculater
  def dothis(x,y)
    puts x+y
  end
end

object = Calculater.new
  @@number = gets
  @@number2 = gets
object.doThis(number,number2)

i'm getting this error,
C:\Users\Spencer_2\Documents\NetBeansProjects\RubyApplication1\lib\new_main.rb:12:
undefined local variable or method `number' for main:Object (NameError)

I'm used to programming in java so I assumed that the doThis(x,y)
parameters are just temporary variables in ruby. Am I wrong?
