Tell me how they did this! 6

Ok, so it probably isn't too difficult.

If you are counting back 10 places, take a look at all the various numbers that ad up to 10...

64,55, 73, 91, 82, 19,28, 37,46

All will have the same symbol, so what's the rest of it, is it time? at first I thought it was detecting the mouse moving over the number, because I pointed with the mouse as I did the math the 'easy way'. So I stopped doing that. Still it gets it right.

I really think it's using elapsed time. Hate to spoil it though. [fish] No Dolphins were harmed in the posting of this message... Dolphin Friendly Tuna!
 
i did notice that all 2 digit numbers that start with one will result in a 9 as the answer, ones that start with a 2 will all result in a 18, 3 will be 27...... limits the possible symbols to 9 or so.....
 
Sheesh.

They just generate a new table each "try" and it is rigged so no matter where you start in the table you end up with the symbol they already chose to show up in the "crystal ball."

Sorry, this thing is ancient. I 1st saw it in the 70s and a lot of kids' "mathemagic" type books cover variations.

Spooky though huh? ooo-EEEE-eeee-ooooooooo
 
2+3=5; 23-5 = 18
2+4=6; 24-5 = 18
2+5=7; 25-5 = 18
2+6=8; 26-5 = 18
etc

Same holds true for
3+3=6; 33-6 = 27
3+4=7; 34-7 = 27
3+5=8; 35-8 = 27
3+6=9; 36-9 = 27
etc

So there is a finite number of possible out comes. Now each of these outcomes has the same picture which change with every click. So for example if your number was 11 the answer would be 9 if you look at 9 the picture changes everytime and that picture is the one that shows. Though I'll admit it had me going for a sec. Good find.
 
Oh wait! I figured it out... if you want the secret, I will share it with you, but try to figure it out on your own first. It's so simple people will miss it.

Darn I wish I had thought of this!

Ok, so fine then, you posted first!

Still, quite interesting. You're all a bunch of brainiac's

Was kind of a nice distraction from figuring out bugs in our programs though !!!!!!
 
I'm guessing we could show it to a group of non-programmer types and they might not ever figure it out. :)
 
Now that just flat cracked me up DrJ... so true that it hurts! [fish] No Dolphins were harmed in the posting of this message... Dolphin Friendly Tuna!
 
Hey, post it over in the hardware stuff, let them chew on it for a bit... lol

it's a joke... oh nevermind! [fish] No Dolphins were harmed in the posting of this message... Dolphin Friendly Tuna!
 
Not so fast... I had the answer first, you just typed faster... [fish] No Dolphins were harmed in the posting of this message... Dolphin Friendly Tuna!
 
oh now stop that... a star for this? Yikes. I know it was you DrJ... take that! [fish] No Dolphins were harmed in the posting of this message... Dolphin Friendly Tuna!
 
This is simple. Whenever you subtract the sum of digits from a two-digit number, the answer is a number which is always a multiple of 9. i.e. 9, 18, 27, 36 and so on...

If you look up in the table, you will see that all these numbers are assigned the same symbol. And that symbol is displayed when you click the ball!

BTW, this post has no connection with Visual Basic!
 
Well sure it does... I'm going to make a clone of this in VB... someday... when I have time... if I get around to it...

(10x + y) - (x + y) = 9x
