    It was pretty straight forward, easy, but the real question is...Could a 5th grader actually solve it, without using a calculator? :)

    Here's another.

    What's opened when closed, and closed when opened?

    A door because when it is opened it is ajar and when it's closed it's not a jar...

    oh wait...

    That doesn't make much sense, now does it?

    It is a door, because when it is opened people close it, and when it is closed, it is opened by people.

    A new one for you:

    There is a prisoner in a room, with two doors and two guards one standing in front of each door. One of the doors leads to life, the other to death. One of the guards always tells lies and one of the guards always tells the truth.

    The prisoner is allowed to ask one question, but he doesnt know which guard is which, or which door.

    What question can he ask that will gain his freedom?

    I actually know this one.

    He asks: "Which would the other guard tell me leads to freedom?" and uses the other door.

    [EDIT: I've got one for you.

    When can 90 + 80 = 2 + 50]

    Door is incorrect. How can a door be opened when it's closed. Makes no sense. The answer is very logical when you know the answer.

    Edit: This will show you how the 13th man appears

    Could it be a switch?

    [The circuit is open when it is closed, and closed when it is open]

    Wait... That can't be it because opening the switch opens the circuit and not the switch itself.


    As far as the 13th guy goes, notice the guy on the far left. They take the top of his head and add it to someone else, while not adding anything back onto him.

    The five on the left, including the one soon to have no hair, replace the five on the far right and, because they don't have to add hair to the guy on the far left, they can use the remaining seven parts to make seven individuals. Five plus one plus seven is thirteen.

    switch is incorrect also! BUT you're looking in the right direction-has nothing to do with electricity. It's a plain everyday thing that some see often others hardly ever. Quite common in Louisiana.

    No not a level crossing-I had to look that up to find out what that was. LOL We call them railroad crossings.
