Somebody has sent me this http://digicc.com/fido/. It gets the answer right every time, but I can't work out how - anybody got any ideas?

I don't think its anything arithmetical because you can fool it.

Jaime,

How did you fool it please? Everytime I tried it, the correct answer was displayed.

Buksi,

I just tried that, typed in the '8' cos I circled the '1' and it picked the '1'.
So I didn't fool it !?!?!?

Aye - just re-edited that post to delete my smug attempt at fooling it which went completely tits up!

I'm sure it's got something mathematical to do with the number '9'.

'9' is special for some reason, saw it on TV

PS: Your smugness can never be deleted Buksi.

You leave a number out and it knows the number cos when it adds your left out number, the total will always be perfectly divisible by '9'.

And it knows what your number is based on the total of the numbers you entered, yours has to be a number that rounds it up to the nearest number divisible by '9', ie 9, 18, 27, 36, 45 etc.

Anyone follow ?

I meant my post was all lies.

Plus all of this made me confused.

1) You type in your non-circled numbers and it adds up to a total

2) You will always be holding a circled number that makes the above total add up to the nearest number divisible by '9'.

ie: 9, 18, 27, 36, 45, 54 etc

Give that man a coconut

It took a while to sink in to my thick head, but I can now see how it works
