And the 1 in front is algebraic, basically mathematicians being lazy. It means multiply by one.

can you move a line to make less than one but more than zero?

(just thought of this, might be more than one solution)

You could make it round so it's ends are touching each other (0)

I edited it. So there is at least one less solution. It used to say "less than one." I added "more than zero."

and I mean from the original problem

ok ...

So to reiterate, to avoid confusion, or just cause:

move one of these lines to make less than one but more than zero.

Is this the same type of solution?

Obviously it's not Pi this time

some same, some different. If all same Miyagi ask for more than three and less than four.

fine. Solve it before I can respond to questions. try this one.

9 9 9 9 9 9

add three lines to make 100

99/99+99

(where + is - and I)

okay, that's all the brain teasers I've got for today.

I'll have a go.

4 men. Man a, b, c and d. They're arranged like this:

a b c | d

The | is a wall that none of the men can see over or through. They are looking to what you see as the right. They cannot turn around.

Each man is wearing a hat. Each hat is either white or black. The men have no idea what colour hat is on their head, but they do know there are two blacks and two whites. When they know which colour hat is on their head they must call it out. The hats are arranged like so:

w b w.. b
a. b c | d
(ignore the dots)

Who knows which colour hat they are wearing?

(this is a long one so forgive me if I left something out)

"b" knows he's wearing a black hat, because "a" doesn't say anything.

If "a" saw 2 hats with the same color, he could say he's wearing the other color, but he remains silent. So he must see 2 different colors. "b" sees a white hat (on "c"'s head), so he knows he must wear a black one.
