This theorem involves Euler's polyhedral formula (sometimes called Euler's formula). Today we would state this result as: The number of vertices V, faces F, and edges E in a convex 3-dimensional polyhedron, satisfy V + F - E = 2.
Euler's Number. There are several famous and helpful irrational numbers. You might be the most familiar with the number pi, or , but there is also the number e. e = 2.7182818284590452353602874713527... The number e is called Euler's Number because it was first used by Leonhard Euler in the 1700s. (Many mathematicians pronounce Leonhard Euler's name as Oiler instead of Yuler). However, another mathematician named John Napier used the number back in the 1600s with logarithms.
