Fun With the Number 9
I hope this isn't a sign that I'm running out of blog material, but the best thing I can think about writing is some fun (?!) mathematical tricks.
Consider the following:
All ten digits, from lowest to highest:
0 1 2 3 4 5 6 7 8 9
All ten digits, from highest to lowest:
9 8 7 6 5 4 3 2 1 0
What do you get when you put them together;
0 1 2 3 4 5 6 7 8 9
9 8 7 6 5 4 3 2 1 0
Multiples of Nine!
Even weirder, when you add up all the digits of a multiple of nine, you get a multiple of nine.
For Example:
9 x 14 = 126. 1 + 2 + 6 = 9
9 x 4258 = 38322. 3 + 8 + 3 + 2 + 2 = 18
9 x 2156754862 = 19410793758. 1 + 9 + 4 + 1 + 0 + 7 + 9 + 3 + 7 + 5 + 8 = 54
Now I got to go wash out my pocket protector for the big D & D game tomorrow. Bye.
