This book is a cumulation of personal research in the pursuit of resolving the fundamental education principle that forces students to "memorize" the multiplication tables of zero thru twelve. Ask any teacher of grade school math why twelve, or ask an math education professor why twelve, and in all cases they can't say. It is hoped that this book and turn the downward spiral of math in the United States, and resort our international status in math and science by show the simple patterns found in math.
