class Program
{
static void num(int A = 5,int B = 4){

int Z = A+B;
Console.WriteLine(Z);
}

{
num();
}

}
}

Answer 1

The meaning of returning is that a value of the Methode get "returned" to the Main Methode(Methode from where you called it). You can see that a value is returned when you can use it in main.
Example:

void num(int A = 5, int B = 4) {
Int Z = A+B;
}
static void Main(string[] args) {
num();
//Error: Main have no variable Z
Console.WriteLine(Z);
}

void int(int A = 5, int B = 4) {
Int Z = A+B;
return Z;
}
static void Main(string[] args) {
num();
//No Error
Console.WriteLine(Z);
}

Answer 2

No, nothing is returned. The calculation result is directly printed on screen, but it is not returned. You should have a line like this

return Z;

In num() body to have the method return something to its caller.

Answer 3

Sry I made a mistake in the Text before. You need to give the returned value of Z to a new variable. Also:

...
int Z = num();
Console.WriteLine(Z);
Sry

Answer 4

Ipang If you enter num(5,3);
Then the sum of 5 + 3 = 8 will be returned
