Opreater overloading method and create a new object in it

Question

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
Score tm1 = new Score(2, 3);
Score tm2 = new Score(4, 2);
Score finalScores = tm1 + tm2;
Console.WriteLine("Round 1: " + finalScores.round1Score);
Console.WriteLine("Round 2: " + finalScores.round2Score);
}
}
class Score
{
public int round1Score { get; set; }
public int round2Score { get; set; }
public Score(int r1, int r2)
{
round1Score = r1;
round2Score = r2;
}
public static Score operator+(Score a, Score b) {
int h = a.round1Score + b.round1Score ;
int w = a.round2Score + b.round2Score ;
Score res = new Score (h, w);
return res;
}
}
}
Why in this method (Score operator +) although it is defined static, but a new instance is created in it
( Score res = new Score (h, w);). We know that when a method is defined statical there is no need to create a new object

Answer 1

A static method is a method where you dont need a instance to call it, but it is still allowed to have a return value (including instantiated objects), meanwhile in a static class you cant instantiate the class, since your class is not static it can be instantiated

Answer 2

static simply means that a method / member belongs to the Class and not the instance.

You are still returning a Score hence return res
