A friend sent this link to me, asking if I could explain how it worked. Boy did she ask the wrong person! But I bet some of you math/computer whizzes out there can enlighten us (please) .

I figured it out! I figured it out! Brain damage.... bah humbug!!!

I'm so smart, I'm so smart S..M..R..T... I mean S...M...A..R..T

ooooookay chrose. . . . So, um, how does it work? Or should we wait a day or so and see if someone else comes up with the answer too? Though I'm really curious to know.

By the way, you are da man!

P.S. Two messages below this one, Phatch gives the answer (hooray!). But I've posted another "brain-challenge" below his posting. So if you want to keep working on this one, just skip his and move on.

YES, YES, I AM DA MAN Actually a guy I work with figured it out quicker than I did and I imagine some will here too. So we'll wait a day or so and see.

I figured it out. If you don't want to know, don't read further.


In any of the 10s groupings, adding the two numbers together and subtracting from the original number always gives you the same number.

30 30-3=27
31 31-4=27
32 32-5=27

and so on. So, each group is correlated to one number in the 10s below it. All of the correlating numbers has the same symbol.

Notice that each time you "try again", the symbol pattern changes, but all of the correlating numbers have the same symbol.

The correlating numbers are all multiples of 9
9
18
27
36
45
54
63
72
81

A friend of mine took an hour or so and figured it out too. Very clever set-up. But her friend took only 5 minutes! However, he sent this very different kind of brain demonstration as a consolation prize. Anyone want to explain this?
