Euler characteristic facts for kids
The Euler characteristic of a shape is a number that describes a topological space, so that anything in the space will have the same number. It is calculated by taking the number of points in the shape, the number of lines in the shape, and the number of faces of the shape. Then, you find the Euler characteristic with this formula:
V is the point count, E the line count, and F the amount of faces. For most common shapes, the Euler Characteristic is 2.
