Unresolved+Problems

Explanation
Here are some problems to think about. When they've been thoroughly solved, we can moved them to the resolved problems.

__**Four 4's**__
You can make the number 1 using four 4's as follows: 4 x 4 ÷ 4 x 4 ÷ 4 = 1 Can you make the number two using four 4's? How about 3? 4? How high can you go? If you get stumped, here's another challenge: Can you find a second way to make 1 using four 4's? A second way to make 2?

Put your name on a card with every equation you find and file it.

__**The Missing Dollar Problem**__ Three students checked into a hotel and paid the clerk $30 for a room ($10 each). When the hotel manager returned, he noticed that the clerk had incorrectly charged $30 instead of $25 for the room. The manager told the clerk to return $5 to the students. The clerk, knowing that the students would not be able to divide $5 evenly, decided to keep $2 and to give them only $3.

The students were very happy because they paid only $27 for the room ($9 each). However, the clerk was confused as he walked away. He thought to himself, "If they paid $27 and I kept $2, that adds up to $29. What happened to the other dollar?"
