This isn't going to work, and it's completely useless.

You can't do what you want to do using a generic method. You're not constraining your Types to only value types. The addition operator is not defined for all possible types that you're allowing (which is basically everything), so you'll get this error. The problem is that you can't use the Int32, Int64, Byte, yada, yada, yada, value types as contraints because they are all structures, not classes. You can only use classes and interfaces as Type contraints, and only classes that expose a parameterless constructor. Structures do not following this rule, so they can't be used.
