Examining Visual Basic .NET's Operators
Simply having a variable with some value in it is not very interesting. Typically, we'd like to be able to perform some sort of operation on that variable or on multiple variables in tandem. For example, in mathematics there are numbers and operators. Numbers are things like 4, 17.5, pi, and so on, whereas operators are things like negate, add, subtract, divide, and so on.
