Our recent numerologist member made me remember this curious calculation, that all kids adore!
12345679 * 9 = 111111111
Now, if you multiply by any number, you get all 2, 3, 4, 5, 6, 7, 8, or 9
12345679 * 18 (this is 9*2) = 222222222
12345679 * 27 (9*3) = 333333333
12345679 * 36 (9*4) = 444444444
12345679 * 45 (9*5) = 555555555
12345679 * 54 (9*6) = 666666666
12345679 * 63 (9*7) = 777777777
12345679 * 72 (9*8) = 888888888
12345679 * 81 (9*9) = 999999999
And another cool detail:
12345679 * 9 * 9 * 12345679 = 12345678987654321
