## Number Theory and Algebra Summary## Tuesday, July 9, 2002We were pleasantly surprised today by two alternate solutions to our problem from the previous day (integer sides of triangles providing integer areas). First, an expansion of our earlier solution was given and then, a more general one that gave all possible solutions in a very elegant way. With that out of the way we turned to some interesting questions that could provide a simplistic entree into some sophisticated mathematics: What numbers can be made by the sum of two (or more) consecutive integers? The solutions to these question involve a survey of some very traditional topics that could lead a class, at any level, far and wide. PCMI@MathForum Home || IAS/PCMI Home
