This book, Magic Square (based on yin-yang principle), teaches the reader the methodology in solving all the magic square from the order 3 to the order N. Firstly, from the yin-yang pair of symmetry-asymmetry, we category all the magic squares into 3 categories, namely the 2N+1, 4N and 4N+2. The categorization becomes the backbone of how we developed the methodology in solving the magic square. Secondly, the yin-yang pairs of movable-immovable and clockwise-anticlockwise are used to solve magic square in few steps. Each category has its own methodology. The methodology derived from this is of...
