Tweet Notice that to show the rules for making these kind of magic squares, I used only oddordered square matrices as examples. What about matrices of even numbers of rows and columns? The rules for these vary. The famous Durer magic square, with the year of the engraving cleverly made a part of a […] […]

In this post, I will begin by discussing “trivial” squares, or squares made by simple rules of following diagonals and wrapping. When I say a square is “magic”, I mean that all rows, columns, and diagonals add […] […]

Tweet Introduction ONE OF THE few things you see on the web these days is how to do a really good magic square. There are many websites that tell you about how spiralling arrangements of sequential numbers on a square matrix is magic, but for me, that’s dull. You are limited to doing seemingly less than a […] […]

Tweet Maple is a robust math environment which can graph, solve equations, and solve for the unknown with the aid of its computer algebra solver (CAS), which is capable of computing exact roots of cubic functions, for example. I wanted to demonstrate for myself that Maple could do various function transformations, such as: f(x), f(x + 1), […] […]
