Got this from the wonders of Facebook, from people whom I (up until now) have considered friends.
“This puzzle”, they claim, “can be solved by an infant in under five minutes. Adults may take up to an hour.”
8809 = 6 5555 = 0 7111 = 0 8193 = 3 2172 = 0 8096 = 5 6666 = 4 1012 = 1 1111 = 0 7777 = 0 3213 = 0 9999 = 4 7662 = 2 7756 = 1 9313 = 1 6855 = 3 0000 = 4 9881 = 5 2222 = 0 5531 = 0 3333 = 0 2581 = ????
I spent nearly three hours staring at it before I snapped and asked Google. It’s STOOPID. But that doesn’t stop me from torturing you lot with it …
Easy, try to find the valor of each number…
0=1
1=0
2=0
3=0
5=0
6=1
7=0
8=2
9=1
2581=2
By an adult, in 1 minut 😀

But have you considered why those numbers have those values?

It’s because adults are more likely to see this as a sums problem, children are more likely to see it as a shape counting problem, particularly the less exposed to sums they have been.
