Add Operator

From GMod Wiki

__add is a type of overloaded operator. You might have noticed that some objects have a function called __add. Well, you don't run __add like this - You run __add by typing the name of the object, a plus sign (+) and the name of another object.

Example

For example, you can add vectors:

Description	Adds two vectors
Used on
Code	myVector=Vector(1,1,1)+Vector(2,2,2)
Output	myVector becomes vector equal to Vector(3,3,3)
