OMG! It can add and subtract! I'm amazed!

Wow...I'm, like, amazed or something.

I still like the old Excel one with the playing cards where you pick one and it removes it or something. That was a good one.

You're obviously not a fan of math.

You picked a terrible thread title, by the way. This math trick was a total waste. Every combination works for this reason:


If you're suppoed to subtract the total of the digits from the original, you end up subtracting incrementally at the same rate you're going up, yielding these results:

0 - 0 = 0
1 - 1 = 0
2 - 2 = 0
3 - 3 = 0
4 - 4 = 0
5 - 5 = 0
6 - 6 = 0
7 - 7 = 0
8 - 8 = 0
9 - 9 = 0
10 - 1 = 9
11 - 2 = 9
12 - 3 = 9
13 - 4 = 9
14 - 5 = 9
15 - 6 = 9
16 - 7 = 9
17 - 8 = 9
18 - 9 = 9
19 - 10 = 9
20 - 2 = 18
21 - 3 = 18
...
27 - 9 = 18
28 - 10 = 18
29 - 11 = 18
...
30 - 3 = 27
...
55 - 10 = 45
56 - 11 = 45
...
66 - 12 = 54
67 - 13 = 54
...
82 - 10 = 72
83 - 11 = 72
...
97 - 16 = 81
98 - 17 = 81
99 - 18 = 81


All numbers between 0 and 9 go to 0.
All numbers between 10 and 19 go to 9.
All numbers between 20 and 29 go to 18.
All numbers between 30 and 39 go to 27.
etc.

Basically, take the first digit and multiply it by nine. That leaves us with all the powers of 9 between 0 and 81, a total of 10 numbers on which you will always land. Note that these are always loaded with the same symbol.

I can't believe you bothered to type all that out. You get a gold star for today!

not only that but everybody is so astounded by it that they just go freaking nuts when they post about it.

meanwhile i figured out it was a mathematical trick on the first go round and im not even a numbers p3rs0n.
