Unless you count the haskell-cafe and beginners mailing lists as sites, I don't know any sites which have the solutions. ;) Problem 3.3.3: Construct a program for division from the specification (m * n) / n = m and prove that it's correct. Sketch of a solution: To define a / n , the usual approach of subtracting n from the first argument until something less than n remains will work. Correctness can then be proven by induction on m .
