Int -> Int -> Int
add a b = a + b

Para explicar, vamos trocar os 3 Int por X, Y, e Z, onde a:X, b:Y e c:a+b

X -> Y -> Z
quer dizer que a função recebe dois parâmetros, X e Y, e retorna Z.

Como em Haskell todas as funções são curryied, a expressão acima também quer
dizer que "add" recebe um parâmetro X e retorna *outra função*, que recebe Y
