We'll be going over a proof of the recurrence relation for the Bell numbers in today's combinatorics lesson. Recall that the bell number Bn is the number of partitions of a set with n objects. By considering an arbitrary partition, and singling out one of its parts, we'll be able to use previous Bell numbers to calculate later Bell numbers with a sum of binomial coefficients multiplied by Bell numbers.
