U Scali je moguće ugnježdavati definicije metode. Sljedeći objekt sadrži metodu factorial za računanje faktorijela datog broja:

deffactorial(x: Int):Int= { deffact(x: Int, accumulator: Int):Int= { if (x <=1) accumulator else fact(x -1, x * accumulator) } fact(x, 1) } println("Factorial of 2: "+ factorial(2)) println("Factorial of 3: "+ factorial(3))

Izlaz ovog programa je:

Factorial of 2: 2 Factorial of 3: 6
