I was looking at some problems in a book asking:
1. How many ways are there to divide a 331 page book into 8 chapters assuming each chapter is an integer number of pages?
2. Prove that for all n greater than 2, C(n,3) = C(2,2) + C(3,2) + ... + C(n-1,2).
I've looked at them for awhile but not really sure how to approach it. Any ideas?
