How to make radio buttons calculations

Hello!

I need some help with how to make calculations on radio buttons.

So, I have these two tables with more choices. The user can choose just one option(radio button) on each of the tables. After the user select a radio button for each of the tables, the selected options (numbers in the right side of the radio button) - option table 1 + option table 2 -  needs to be calculated as a sum. I need to know how can this be done in Acrobat Pro.

Thank you !!!
