 1. Using any combination of parentheses and the operation symbols +, -, x, and ÷, how can you arrange the numbers 7, 7, 7, 7 and 7 into a mathematical expression equal to 7? 2. What number is next in this series: 3, 4, 7, 11, 18, 29, ...? 3. Scientists in Antarctica that study and film wild life on that continent have never filmed a polar bear attacking a colony of penguins.  Why not? 4. Name a sport where the defensive team keeps possession of the ball. 5. Three men check into a hotel.  The manager quotes the room at \$30.  The three men pay \$10 each.  After the men go up to the room, the manager realizes that he overcharged them, the room is only \$25.  He sends the bellboy up with \$5 to refund to the men.  The bellboy decides he can make some money.  He pockets \$2 and gives the men back \$3 (\$1 each).  The men divide up the money \$1 each. Now, each man paid \$9.  \$9 times 3 = \$27.  The bellboy pocketed \$2. \$27 and \$2 totals \$29.  Where's the missing dollar?
