Next example will print two values and their sum.

Module Example
    Sub Main()
        Dim value1 As Integer
        Dim value2 As Integer
        Dim sum As Integer
        value1 = 1
        value2 = 2
        sum = value1 + value2
        '
        ' or :
        ' Dim value1 As Integer = 1
        ' Dim value2 As Integer = 2
        ' Dim sum As Integer = value1 + value2
        '
        ' or :
        ' Dim value1 As Integer = 1, value2 As Integer = 2, _
        '     sum As Integer = value1 + value2
        '
        Console.WriteLine(value1 & " + " & value2 & _
                          " = " & sum)
        '
        Console.ReadLine()
    End Sub
End Module

Output :

 1 + 2 = 3

The above example illustrates the use of the addition operator +.

Other arithmetical operators are :
- subtraction operator -
- multiplication operator *
- division operator /
- integral division operator \
- modulo operator Mod
- exponential operator ^

All the above operators use two operands ( left and right operator ).

The concatenation operator & will combine two Strings ( to one String ).

The nextline operator _ can be used to maintain readability of your code.
The compiler interprets the instruction on the line following an underscore as if it was on the position of that underscore.

A declaration line can contain more than one variable. After the type specifier ( of the declaration of some variable ) a comma is place, followed by the declaration of the next variable.
