Thanks a lot for this.
Just to clarify (and ignoring the flip, which I can solve by rewriting the checkNum function) - is this an example of currying?

Hey Matt,
if what you want is
[checkNum 1 list2, checkNum 2 list2, etc.]
then
map (flip checknum list2) list1
is what you want (flip signature being :: (a -> b -> c) -> b -> a -> c)
