Question 1208923: Tripper lives in a house on a straight street. For years, there have been 16
houses on his street to the right of his house and 17 houses on his street to
the left of his house. Last year, 5 new houses were built on the same street
even further to the left of those houses to the left of Tripper's house. If
these are the only houses on this street, how many houses are on this street?

This is an easy problem.  But some people will get the wrong answer.  Some
people will add the houses that were left and right of Tripper's house that 
were on the street before last year, and they will add the 5 new houses.  But
they will forget to add 1 for Tripper's own house!

But I'll bet you won't forget to add 1 for Tripper's own house!
