In order to effectively view the Square of Nine Table the Dimension, Zoom and Decimal controls must be used in a coordinated manner. The numbers running horizontally and vertically from the center have a squares of quarter numbers, e.g. 2.5, 4.5, 6.5, etc) proceeding downwards to the right at 45 degrees, "odd" half numbers proceeding upwards to the left. will populate the other two "corners" of the square, "even" half numbers (e.g. Numbers being the squares of half numbers, e.g. Numbers being the square root of whole even numbers (2,4, 6, 8, etc.) will proceed in the opposite direction beginning with 4, 16, 25, 36, 64, 100, and so forth. It is constructed by listing an ascending sequence of numbers beginning at 1 in the center of the table, then 2 to its right, 3 above 2, and continuing along the outside of the square in a clockwise direction until the set amount of numbers have been added to the table.Īfter the first complete rotation, the square will have 9 in its lower left corner, after the second rotation 25 will be in the lower left corner.Īs the table grows, numbers being the squares of whole odd numbers (1,3,5, 7, etc.) will proceed in 45 degree diagonal line down and to the left of the center (1) beginning with 9, 25, 49, 81 and so forth. The Square of Nine table, which has also been referred to as the Odds and Evens Chart or Pythagorean Square, is essentially a square root calculator.
