Here's a much more difficult, but much more interesting problem. If you put n dots on a circle, and connect them with all the possible chords, what's the maximum number of regions the circle can be divided into? Except that's not the case. Here it is for six points on the circle. You have to be a bit careful where you put them to get the maximum number of regions. Allowing three of the chords to cross at a single point shown with a red dot on the left below is not acceptable. That's because it gives you fewer regions, and the problem statement specifies the maximum number of regions: And lo and behold, there are only 31 regions, not 32 count them!

Poking around the internet, I've determined that this formula gives the sum of the first five numbers in successive rows of Pascal's Triangle or the sum of the entire row, if there are less than five.
The notation inside the summation, including the parentheses, can be read as "the number of combinations of n-1 things taken i at a time". It generates the well-known binomial coefficients that form Pascal's Triangle. The triangle is easily constructed - note that each number is the sum of the two above it. That's why the sum of all the numbers in any given row is a power of two - because the numbers in each row contain the numbers in the previous row twice. Things in mathematics are marvelously interconnected.
