9…18..27..36..45 = 135 = 9..and 1 + 3 + 5 = 45 = 9 90..81..72..63..54 = 360 = 9. — — — — — —- — 99 99 99 99 99 495 = 18 = 9.
So 9² = 81 …81² = 6561 = 19 = 9 …9x2 = 18 …18² = 324 = 9.
9x3=27 …27² = 729 = 18 = 9. 9x4 = 36 …36² = 1296 = 18 = 9.
And so with every multiple of 9—say 45, 54, 63, 72, etc.
Thus 9x8 = 72 …72² = 5184 = 18 = 9.
And further:
18 27 36 72 18 27 36 72 —- —- —- —- 144 = 9 189 = 18 = 9 216 = 9 144 = 9 18 = 9 54 = 9 = 108 = 9 504 = 9
324 = 9…18 = 9 729 = 18= 9 1296 = 18 = 9 5184 = 18 = 9 108 108 —— 864 = 18 108 = 9 ——- 11664 = 18 = 9.
And so the cubes:
27²=729x729=18=9 18²=324=9 9²=81 81²=6561=18=9
729 324 6561
