Counting It Twice.
Schattschneider, Doris
College Mathematics Journal, v22 n3 p203-11 May 1991
Provided are examples from many domains of mathematics that illustrate the Fubini Principle in its discrete version: the value of a summation over a rectangular array is independent of the order of summation. Included are: counting using partitions as in proof by pictures, combinatorial arguments, indirect counting as in the inclusion-exclusion principle, and double counting. (10 references) (JJK)
