OT-But at least it is related to Math

This is one of the strangest things I have ever seen. It may be the easiest
to explain but so far, I haven't come up with a good explanation for myself.
Give it a try and you with the larger brains, please explain it to us lower
thinkers.

twice it didn't pick the right symbol. so it didn't work for me. oh yeah I had my brain wave hat
blocker on. duh, silly me....

Spooky, until you realise that all it is doing is forcing your "random"
number choice to be one of only a few specific numbers once you at the two
digits and subtract them. Then all those limited numbers have the same
symbol in the table. i.e.

11 = 11 - 2 = 9
12 = 12 - 3 = 9
13 = 13 - 4 = 9
14 = 14 - 5 = 9

19 = 19 - 10 = 9
20 = 20 - 2 = 18
21 = 21 - 3 = 18

etc

so in the table 9, 18, 27, etc are all the same symbol, which "magically"
appears.

Simple but fun, especially for kids :-).


Very best wishes and clear, dark skies.

The only thing spooky is the witch's cackle while the symbol is displaying.
No, I would never think of anything supernatural about this but it is clever
as hell. But then again, do brain wave helmets come in blue?

Thanks for the explanation. What throws me off is that the answers APPEAR
random. Well, I guess I better pick up my 4th grade daughter's math book
and start learnin'. Thanks again.

I guessed the right explanation after the first try and then went back
and did it again only to find myself proved wrong! After another try I
realized they are also switching the symbols around on every iteration
to hide the trick.

A two digit decimal number is 10a+b, a being 1 to 9 and b being
0 to 9. Add the two digits together and you get a+b. Subtract
a+b from 10a+b and you get 9a. All the numbers evenly divisible
by 9 had the same symbol.

Here's a slightly more obscure one, but still easy to figure out:

It won't be in a 4th Grade maths book because it's a commonplace trick -
what would be educative would be to work out how to use the same effect in
Octal base, or in Bse 5 or maybe even in Binary - see the trick and find the
pattern behind it!

The trick is, of course, is that none of the first set of cards sppear
in the second set. The psychology is that by concentrating on one
card you don't remember the others and when the second set of face
cards appears you fail to notice that you didn't see any of them
before.
