The Mind Reader

weather: mostly cloudy
outside: 7°C
mood: amused
The Mind Reader. Click on "Flash"; choose "flash mind reader" in row 3, column 2. The "Shaman Mindreader" is the same thing.

Don't touch your mouse or keyboard when you do it. It's spookier (to you) that way. =D

It's a cheap parlour trick that takes advantage of the fact that most people don't understand properties of decimal numbers all that well. I've always been fascinated with number properties and I knew about this one from 5th Grade. It's still fun to watch it creep people out. =)

Nah, they didn't figure out. They did email a bazillion of their friends with the url though.

Kids. ;)

It's very cute. :) I recognized the property as soon as I read the instructions. I love tricks like this, though.

Re:
The multiples of 9 are the most interesting.

When I was learning the multiplication tables in first grade, I learned up to the 5's, then I learned the 9's before the 6, 7, and 8's. =)

And in Accounting, when your balance sheet doesn't balance, you take the difference of the DRs and the CRs. If the diff is a multiple of 9, you look for a transposition error =D

Hee. :) I learned the tables in a similar fashion; I think I learned 2, 5, 3, 4, and 9 before the rest.

I've learned a few other tricks with regards to balance sheets; yay for data entry teaching you interesting things about numbers. :)

I thought it was interesting, too. I didn't figure it out from the instructions but when it got the symbol I had chosen I worked out why on pencil and paper.

What surprised me was that when I picked a different number, which had a different final number and a different symbol, it was correct as well.

Until I had a look at the symbol my first number now has.

Still, interesting :)

I'm pretty sure I have this figured out, but if you're doing mass-emails with the answer, then...

I learned the 2 times table first, then I think 7, then 9. Who knows why.
