[korme]

How does it work every time????? SEE FOR YOURSELF.

Just a pattern of symbols. Goodtimes, though

[korme]

But it's not like it is getting lucky. It gets mine right every single time.

It swaps the symbols every time so that all of the mathematical combinations are covered.

interesting :D

No, but good try.

Think about it, you are never giving your number away, so how is it going to know? if you look at the chart, what if your number was one below it? It is a different symbol, yet still brings up the number you had in your head.

[digamma]

you are always going to end up with a multiple of 9, so 81, 72, 63, 54, etc. all have the same symbol. it switches that symbol every time, but if you do it a few times, you will notice that these all have the same symbol.

clever, but not magic.

[korme]

Ok, digamma but how would it know, for instance, that my number is a multiple of 9?

[digamma]

because every answer is a multiple of 9.

99-18=81
98-17=81
97-16=81
...
89-17=72
88-16=72
87-15=72
...
79-16=63
78-15=63
77-14=63

and the list goes on.

it'll always end up being a mulitple of 9

beat me to it....

For about two minutes, it managed to both scare and amaze me. Pretty cool.

Yep, the only possible answers are 9,18,27,36,45,54,63,72,81 and they all have the same symbols

To add to that, every two-digit number in our number system is written as a group of tens and a group of ones.

49 = 4 x 10 + 9
55 = 5 x 10 + 5
yz = y x 10 + z

So if you subtract the sum of the two numbers you would get...

49 = 4 x 10 + 9 - (10 + 9) = 4 x 10 + 9 - 10 - 9 = 4 x 9
55 = 5 x 10 + 5 - (10 + 5) = 5 x 10 - 10 - 5 = 5 x 9
yz = y x 10 + z - (y + z) = y x 10 + z - y - z = 9 x y

So the answer will always be one of the multiples of 9 under 100. (Then look at where all of the yin yang symbols are.)

I bet this post interested nobody. My explanations of math tricks never seem to amaze my students as much as the tricks.

EDIT: It looks like it isn't always yin yang symbols. But the symbols for multiples of 9 are always the same.

That's very clever. I actually figured out the math by myself. But changing the symbols had me fooled. Did the quantitative, but failed on the qualitative. :)

Hmmmm. I missed those threads. ("Check this out" usually makes me kinda move on.) Good catch! :)

This is a high-tech version of an email that's been on the internet since as long as I can remember. The email had you scrolling down to find the answer.
