Currying n arguments create n functions

I have a function

//normal version
let addTwoParameters x y = 
   x + y

translate to curry version it looks like:

//explicitly curried version
let addTwoParameters x  =      // only one parameter!
   let subFunction y = 
      x + y                    // new function with one param
   subFunction                 // return the subfunction

What when I have a function with 4 arguments like:

let addTwoParameters a b c d = 
       a + b + c + d

How the currying version would be?

It would look like this:

let addTwoParameters a  =
    let subFunction1 b = 
        let subFuction2 c =
            let subFuction3 d =
                a + b + c + d
            subFuction3
        subFuction2
    subFunction1
