Anything Goes

My dad sent me this text message and after reading it, I said to myself, why didn’t I notice this before? The wonders of text messaging, you get to know stuffs that you never knew about before. So check this out, when multiplied by any other number, it returns to 9.

9×1 = 9 (9+0 = 9)

9×2 = 18 (1+8 = 9)

9×3 = 27 (2+7 = 9)

9×4 = 36 (3+6 = 9)

9×5 = 45 (4+5 = 9)

9×6 = 54 (5+4 = 9)

9×7 = 63 (6+3 = 9)

9×8 = 72 (7+2 = 9)

9×9 = 81 (8+1 = 9)

What do you think? Interesting?
