# Curried Functions

Functions in Haskell are also free to **return functions** as their results. This brings us to **curried functions** which take in **one argument at a time **and **return a function** that takes in additional arguments. Actually, all functions in Haskell with multiple arguments are applied this way (unless explicitly stated otherwise) – the function is first applied to the first argument and returns another function that is then applied to the second argument and so on. Let's explore this with an example `multiply` function that takes in three numbers and multiplies them:

That is, `multiply`

takes the argument `x`

of type `a`

and returns another function that takes in the argument `y`

(also of type `a`

) and returns another function that takes in the argument `z`

(also of type `a`

) that then returns the final result (also of type `a`

). To avoid unnecessary parentheses, the function arrow `->`

associates to the right by convention, while the function application associates to the left:
