So how the hell does *this* work. Linky and Dinky have a card trick, and I've figured out how that works, but I have no clue how this works.......

Thanks,

That's been here before, in slightly different presentation. Hint #1: look at the numbers that you get from the arithmetic they ask for - what do they have in common?

TheDiddleyMan

I don't know what you are asking. Are you saying that you are only supposed to choose numbers that repeat digits, e.g. 55 or 66. I chose numbers like 73 or 96 and it worked. Hell, I tried single digit numbers, like 9 (9-9=0) and it worked.

I'm probably missing something, and making myself look stupid.
Can you link to the thread you are talking about?

Thanks,

Kevin

doesn't work for me the mindreading, maybe i don't have one .
but take a 2 digit number, call them a and b, your 2 digit number would then be 10*a + b. Substract a and b 10a+b-b-a=9a. So the answers is always a multiple of 9

That's what I was getting at - now look at their grid.

No thanks but it still fails to read my mind though

lol, I also got wowed by that the first time.

I wonder if this would pass as a "miracle" for the less skeptical..

Any time people ask you to do mathematical calculations before making a prediction, work out the general equations ahead of time (i.e. do it for the number ab where a and b can each be any integer from zero to 9). It's always just simple algebra and usually once you do this the inner-workings of the trick become obvious.

He-he, you're not concentrating on the "correct" symbol are you!
