That is so cool.  I don't know what the theory behind it is, but can't wait
to figure it out.

However it works, there are only certain numbers which can be answers, and
they all have the same symbol.  Interesting.

Very weird!  My husband stood over my shoulder and did the math -- I clicked
the mouse and it still worked.  Even if I concentrated on a different shape,
his would show!  We both tried doing different numbers at the same time and
it would show the picture of the person clicking the mouse but you had to do
the math!  If we just concentrated on a shape, no match!

Answer will be 9,18,27,36 etc  The nine times table.  You will note the
symbol for those is always the same.  To keep you from seeing it, the
symbols shift around but those always match each other.

No.  But it is wrong more than it is correct.

gee.  it didn't get any of them wrong for me.  i thought it might have
something to do with pointing my cursor at a number or symbol.  i tried to
trick it by pointing to the wrong number/symbol while doing the selecting,
adding and subtracting in my head.  it still worked.

i'm satisfied---it's maaaaaaaagic.<giggling>

Its a math formula.

pick any 2 digit number....add the two digits together and subtract
from the original 2 digit number and you will always get a number
divisible by 9!

Notice that each time you attempt their "trick" that every number
divisible by 9 has the same symbol.  The symbol may change with each
attempt, but it is the same for each of those numbers.

"The Magic Number 9" is the title of a book I've owned
for more than 40 years.

In elementary school (grades 5-6) we were taught how
to use the number nine to check addition, subtraction,
multiplication and division.  That goes back 59-60 years.

Chief, when I worked in the installment loan department of a bank, and we
were totaling accounts monthly, I learned if the difference of two totals
could be divided by nine, you most probably had a transposition somewhere.
Made it easier to know where to start looking.

It is even easier that that.

If the difference is 9 the transposed digits will be one digit apart.  12:21
23:32  ETC

If its 18 two digits apart, etc.  Adjust as needed for hundreds thousands
etc.

That's exactly what my teachers called it.

There aren't many around today who have heard
the term (or who will admit to having heard it).

I'd mention it to my son's teachers in the 80's
and I see the BIG question mark appear on
their faces - what the hell is he talking about?.
DiWitt - 18 Jan 2005 23:46 GMT
I tried to teach my son's fifth grade teacher how to do this and it was in
the days of Prodigy and long long modem times.  Couldn't really remember how
to do it and he had never heard of it. I think once calculators became so
prevalent, more complex math problems were done on them and casting out
nines to check your work became obsolete.  Heck, when I took the SAT's, it
was done with pencil and scrap paper!  Now the kids get to use a calculator!

These days I enjoy teaching math teachers how to multiply a 2-digit
number by 11 (in their head) and watching their "Why didn't I think
of that?" expression.

The nurses at the hospital always made me nuts the way they did calculations.
I wanted to set up a math class for them all and teach them about the
numbers and how to "see" easier ways of doing stuff.  Then one day one of the
nursing students did come calculating by classic short-cut math style.  I was
so happy!  Turned out she'd been a math teacher before going back to school
for nursing.

except the symbols for every ninth digit change above 81 because, according
to the formula, you can't get a result above 81.
