How many edges are there

We have removed one vertex — the one between the two edges — so there are now V - 1 vertices. We have removed two edges, so there are now E - 2 edges. Finally, our chosen face has merged with the exterior face, so we now have F - 1 faces. So V - E + F has become (V - 1) - (E - 2) - (F - 1) and
