The Eulers formula is as simple as this

• On any three-dimensional shape, the number of
  vertices minus the number of edges plus the
  number of faces will always equal two. AND I MEAN
  ALWAYS. Fascinating information, huh?

Lets try it.

• Lets try it with a cube! In case you dont
  know, a cube has 8 vertices, twelve edges, and
  six faces. First, subtract the number of edges
  from the number of vertices (you will get a
  negative here.) Thats just 8 12 -4. Then,
  add the number of faces to that. Negative four
  plus six is two. See? The answer will always be
  two.

Lets get fancier with it. Well use an
Icosahedron.
