What does "static" mean in methods

Question

Why do we need to use a static keyword when making a method?

static int x() {
//return
}

What is the difference with static and without static?

Answer 1

When a method is static then it can be invoked directly from the class level without creating an object. This is the reason for making a main() function/method static. Another example is the WriteLine() method that is called/used without creating any object.
