Number Graphs

For this last session of the Fall 2014 meetings, we explored a type of number puzzle involving labeling undirected graphs.


Some of the questions we explored:

  • How can we solve an arithmagraph puzzle using addition?
  • How can we solve an arithmagraph puzzle using multiplication?
  • What types of arithmagraphs can’t be solved?
  • How many different ways are they to specific types of arithmagraphs?
  • What are some fool-proof ways to solve arithmagons?
