Ask Newton!

Explanation:

The law of gravitation states that the attractive force between two masses is proportional to the product of their masses, not the sum of those.

Perhaps the addition might come when you are finding R. The distance R is the distance between the two centres of masses. You could also add up the radii of both objects (assuming they are spheres) and the shortest distance between their surfaces to find R.
