It doesn't work, no matter what I type

Hello,

I do't know how to fix this problem. I've tried everything and all I get is error message.

math.rb 
@pi = nil
@e  = nil
@sqrt = nil
module Math
  puts Math::E = @e
  puts Math::PI = @pi
  @sqrt = Math.sqrt(9)
end

Try doing it after "end", instead of doing it inside the module.   :wink:
