Topic: Arithmagons

Arithmagons are polygons with a circle number on each vertex and a box number on each side such that each box number is the sum of the two circle numbers adjacent to it.

Notice that the sum of the two circle numbers on either side of a box number is equal to the box number. This is the basis of all arithmagons.
