sigA: int -> int In [ ]: let siga sgn siga sigB: int -> unit In [ ]: let sig = sgn sig sigC: int -> string In [ ]: let sigc = sgn sigc sigD: unit -> string In [ ]: let sigD sgn sigD sigE: string -> string In [ ]: let sige sgn sige sigF: int -> bool -> float -> string In [ ]: let sigF = sgn sigF

Answer 1

let sigA a = a+2

let sigB a = printfn "%i" a

let sigC a = a.ToString();;

let sigD = reader.ReadLine()

let sigE (s:string) = s.chars(2)

let sigF 3 : true : 0.5 = "hi";;
