Magic Square
The Magic Square has a Chinese origin and has for long been used in both school and recreational mathematics. It is simple and engaging: Consider the numbers {1, 2, 3, 4, 5, 6, 7, 8, 9}. How can we arrange them to a square so that the sum of the three numbers along each row, each column, and each diagonal are all the same? As a warm up, one can ask children to add up the following: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 =? There are of course many different ways to add up the n
