After finding the answer in about five minutes, I looked in the thread for the answer.
I never would have thought to look at the number of "holes," but I still found the same answer.
Basically, we're given that:
0000=4, so (0)=4/4=1
1111=0, so (1)=0/4=0
2222=0, so (2)=0/4=0
3333=0, so (3)=0/4=0
5555=0, so (5)=0/4=0
6666=4, so (6)=4/4=1
7777=0, so (7)=0/4=0
9999=4, so (9)=4/4=1
Since (4) doesn't appear on the left at all, that is unnecessary to find.
But in order to find (8), take any four-digit number with an 8 in it and solve.
Since 8096=5, (8)+1+1+1=5, and thus (8)=2.
And currently studying for a MA in math education. |

I think it would be more appropriately named puzzle rather than problem, as this is not exactly mathematic. |

I was way over-analyzing this. I started making equations out of the 4 numbers and switched around operations to see if I could get the answer. I gave up after 10 minutes. I read comments and bashed myself in the head with a tack hammer. |

I think there is something wrong with my thinking because I used math and removed the second column and third row down since I deemed that to be false statement
and got the answer 2
and dont know how to do a spoiler but trying anyways
/spoiler/
1 2 3 4 5 6 7 8 9 0

After 3 minutes, gave up and looked in comments for answer. I seriously would have never gotten this.

Later that week, you murder the brother of the deceased from the first funeral. Why?*
So that there'll be another funeral, and hopefully the person you were attracted to will be there again, and this time you can talk to them? |

So you see the person again at the next funeral! That's not sociopathic, that's good planning. |

Nearly immediately because I always used to count the "holes" in numbers and letters in each sentence when I was bored in school... that's probably more pre-school than higher education but eh. |

OK, second pop-psychology problem of the day:
You're at a funeral. You see someone you're attracted to at the memorial service amongst the assembled mourners. However, before you can speak with them, someone else distracts you. When you do eventually manage to return your attention to the object of your desire, they've disappeared. You ask around, and find out that they left, and that no-one knows how to contact them.
Later that week, you murder the brother of the deceased from the first funeral. Why?*
[* NB: If you know the answer, apparently, that means you have sociopathic tendencies. At least in pop-psych world]

If true, it'd be an interesting demonstration of the differences between the perceptions of pre-school children, who've not yet had the chance to over-learn the association between abstract symbols like numbers and their assigned meaning, and adults who have.
I've seen this problem before, though, alongside the surprising statement that pre-schoolers can solve it quickly. I've never seen any actual figures to back up the assertion that pre-schoolers do solve a problem like this as quickly as claimed, however. |

I don't think I could have done it without the description of the problem. |

I must have the brain of a pre-school child. Is that bad or good? |
