>I got the information below from a training/video site I subscribe to. Why would they make a language harder to understand than is needed? What is the reason for having "++" to add 1 and "+=" to add 10? Why not just i+1 or i+10? Doesn't make sense to me. And, this actually is C#, not C++, but I didn't see a C# forum. Unless they are the same?

C# is in .NET forum.

Also it is important in C# (C++) where do you put ++ or -- (before or after the variable). It changes the sequence of what comes first.
There are several complex operators in C#.

See them C# operators with explanations.
