Graphic reasoning, which of the following pictures can be filled with question marks?

Looking in parallel: one point in the circle+one point in the circle = two points in the circle.

Inside the circle 1 point+3 points outside the circle = 2 points outside the circle (inside and outside can be regarded as positive and negative respectively)

Two points inside the circle = two points outside the circle = no point inside the circle.

Choose the fourth one.

It's the same vertically.
