6392 + 1742 + 8522 = 9362 + 4712 + 2582 (counter-diagonals) 6542 + 7982 + 2132 = 4562 + 8972 + 3122 (diagonals) 6932 + 7142 + 2582 = 3962 + 4172 + 8522 (counter-diagonals). This property was discovered by Dr. Irving Joshua Matrix [3], first published in [5] and more recently in [1]. We prove that this property holds for every 3-by-3 magic square, where

In 1972, Hudson [2] gave a method for the construction of pandiagonal magic squares of order 6t±1. In this paper we give the definition of pandiagonal Latin squares and the methods for the construction of self orthogonal pandiagonal Latin squares of order 4, 8, 9, 27 and prime p⩾5. One can use the technique of Kronecker products for the construction of

Discovering the Magic of Magic Squares
The Mathematics Teacher, 2007A collection of problems that allow students to investigate magic squares and Latin squares, formulate their own conjectures about these mathematical objects, look for arguments supporting or disproving their conjectures, and finally establish and prove mathematical assertions.

Johnny Carson docs a routine that is a take-off on the answer man. Instead of answering questions, however. Johnny is presented with an answer and he supplies a question having that answer. An analogous situation can be presented to youngsters. Let them play Johnny's part. the part of the question person. Suppo e that you orally give them, say, fifteen.
