I know it has something to do with types,

Right! :)

but whenever I try to add a type signature to the functions it just messes everything up even more.

This works: let a :: [Double]; a = [-1,2,-6,2]

This works too: let a :: Num a => [a]; a = [-1,2,-6,2]

What do you think are the pros and cons of either?
