Hi Miranda,
How to calculate the sum of list of lists in Haskell?
What do you mean by this? What is the value of a list? If you mean sum the numbers such that [[1,2],[3,4]] = 1+2+3+4 then you are able to ask two alternative questions - how do i convert a list of lists to a list, and how do i sum a list. Both can be answered by Hoogle: http://haskell.org/hoogle/?q=%5BInt%5D%20-%3E%20Int The list of lists to a list is a bit easier so I'll leave you to solve that one :) Thanks Neil
