Combining variables

I have created some questions that use radio buttons in their answers. Each radio button I have set to a variable of different values. My problem is: I want to be able to display a sum of all the buttons and I would like that sum to be visible as the user clicks the radio buttons. IE if I have 4 buttons and each button represents a number 1-4 I want to display the sum of the buttons selected.(button 1 + button 4) =5 How can I do this?
