Another Halloween Game

Maybe on the law of averages? I tried it a few times and it was wrong twice. Still very cool, though.

It looks like there are only a limited amount of possible answers. (ex: 10-1=9, 12-3=9 or 87-15=72, 88-16=72)

I tried it three times with my resulting numbers being 63, 9, 72. In all three cases the symbols are the same for each of these numbers. In the last try, the symbols were rearranged, but they were still the same for each of the numbers.

Tintaglia was on the right track…basically the answer is always a multiple of 9, on their chart multiples of 9 are always assigned the same symbol, and this is the symbol which is shown at the end. But the assigned symbol changes each time you try it, which makes it harder to pick up on what the program is doing.

To see why it always has to be a multiple of 9, consider the following:

1) A 2 digit number can be symbolized by XY, where Y is the least significant digit.

2) We’re told to add the two digits together (X+Y) and subtract that from the original number (10X+Y), to get the final number (FN).

3) If we express this as an equation we get: (10X + Y) – (X+Y) = FN

4) If we combine the terms, we get: 9X = FN

5) This means than FN (the final number) is always a multiple of 9, since X is a number from 1-9.

😆 Kinda takes you back to your old algebra days, huh? 😆

😆 Come to think of it, I don’t remember what they taught us in algebra class back in jr. high. I just remember the problems about the trains passing each other at different speeds…

All I can remember is: speed = distance divided by time:-/

Your math was my “scare” for the day, Mimi. 😉 😆
