Riddle:
Taking that internship in a remote mountain lab might not have been the best idea. Pulling that lever with the skull symbol just to see what it did probably wasn't so smart either. But now is not the time for regrets because you need to get away from these mutant zombies...fast. Can you use math to get you and your friends over the bridge before the zombies arrive? Alex Gendler shows how.
Answer: At first it might seem like no matter what you do, you're just a minute or two short of time, but there is a way. The key is to minimize the time wasted by the two slowest people by having them cross together. And because you'll need to make a couple of return trips with the lantern, you'll want to have the fastest people available to do so. So, you and the lab assistant quickly run across with the lantern, though you have to slow down a bit to match her pace. After two minutes, both of you are across, and you, as the quickest, run back with the lantern. Only three minutes have passed. So far, so good. Now comes the hard part. The professor and the janitor take the lantern and cross together. This takes them ten minutes since the janitor has to slow down for the old professor who keeps muttering that he probably shouldn't have given the zombies night vision. By the time they're across, there are only four minutes left, and you're still stuck on the wrong side of the bridge. But remember, the lab assistant has been waiting on the other side, and she's the second fastest of the group. So she grabs the lantern from the professor and runs back across to you. Now with only two minutes left, the two of you make the final crossing. As you step on the far side of the gorge, you cut the ropes and collapse the bridge behind you, just in the nick of time.

Riddle:
Ms. Dell is a math teacher at a high school. She always gives her students summer homework. One year, her students are SO tired of summer homework, and they want her to stop giving it to them. Ms. Dell promises a riddle to the students; whoever gets it right will not get summer homework. The riddle went like this: Add me to myself, and multiply me by four. Divide me by eight, and you will have me once more. What number am I? All of her students gave different answers, but nobody received any summer homework. How is that possible?
Answer: All numbers work with Ms. Dell's riddle! ((x + x) * 4) / 8 will always equal x.
Riddle:

Which teacher was that?
Answer: It was Vanessa's math teacher who failed her. Math is mostly numbers, so the girl's math teacher could understand everything and check the exam.

Riddle:
Wendy and Maverick are participating in a mathematical game show. Their scores are tied, so whoever gets the last riddle correct wins. The riddle goes like this: I am thinking of a number. It is a five-digit whole number. It can be read the same way forwards, backwards, and upside-down. The second digit is half of the third. The last digit is the product of the first and last digits. And the sum of all five digits is 10. What number am I thinking of? Wendy says, "12,421". Maverick says, "10,801". Who is correct?
Answer: Maverick is correct. The number is 10,801. This is why: Both numbers meet most of the requirements, but 12421 does not meet the second requirement because it CANNOT be read the same way upside-down as right-side-up. Many think 10801 does not meet the third requirement, but 0 CAN be half of 8 if you cut 8 in half horizontally. This way, you will get two zeros, and 10801 DOES meet the third requirement. Since only 10801 meets all the requirements, it is the correct answer, and Maverick is right!
