Subject: Class variables

I have tried to deal with class variables but I received weird output
the code is here and below it is the output

class ClassVariable
attr_accessor :total
@@num1 = 0
@@num2 = 0

def getValues
 puts "enter a number"
 @@num1 = gets
 puts "enter a number"
 @@num2 = gets
end

def sum
 @@num1 + @@num2
end

end

obj = ClassVariable.new
obj.getValues
puts obj.sum

-- output
enter a number
4
enter a number
5
4
5

as u can see in the output it just repeats them and did not sum them up
and returns the summation value.
any idea?
Regards
Shuaib
