3.  Take the first 100 primes and multiply them all together.  What would be the digit in the ones (units) place of the product?  [This is easier than it looks.]
4.  A man was changing a tire when he stumbled on the hubcap holding all the nuts holding the tire in place and they all fell into a nearby sewer drain.  Just as he was cursing his fate, a passing boy made a suggestion which enabled the man to drive off (in his own car).  What was the boy’s idea?
