❔ How to calculate event expression?

like 
c#
var result = a+b-c+d-c+d-b+a;
c#
var result = a+b-c+d-c+d-b+a;
a,b,c,d are all events, and each of them contains more than one method. So what is result like?

What type are they?

They are events. Like: 
c#
delegate void F();
event F a, b, c, d;
c#
delegate void F();
event F a, b, c, d;

although I don't know if you can add and subtract delegate types like that

But I just see the result but I don't know the rule.

REPL Result: Success
delegate void F();

F a = () => Console.WriteLine("a");
F b = () => Console.WriteLine("b");
F c = () => Console.WriteLine("c");
F d = () => Console.WriteLine("d");

var result = a + b - c + d - c + d - b + a;
result();
delegate void F();

F a = () => Console.WriteLine("a");
F b = () => Console.WriteLine("b");
F c = () => Console.WriteLine("c");
F d = () => Console.WriteLine("d");

var result = a + b - c + d - c + d - b + a;
result();
Console Output
a
d
d
a
a
d
d
a

a + b - c + d - c + d - b + a
a + b - c + d - c + d - b + a
If we think about it like algebra 
+ a
+ b
- c (doesn't do anything)
+ d
- c (doesn't do anything)
+ d
- b (removes b)
+ a
+ a
+ b
- c (doesn't do anything)
+ d
- c (doesn't do anything)
+ d
- b (removes b)
+ a
So the result is that + b and - b cancel out, and the - cs don't do anything. 
+ a
+ d
+ d
+ a
+ a
+ d
+ d
+ a

You dismiss a condition, the event can contain more than one method. I want a more general rule like we know 1+1=2.
