Boolean value with And and Or

Option Strict On
 Imports System
 Module Module1
    Sub Main( )
       Dim x As Integer = 5
       Dim y As Integer = 7
       Dim andValue As Boolean
       Dim orValue As Boolean
       Dim xorValue As Boolean
       Dim notValue As Boolean
       andValue = x = 3 And y = 7
       orValue = x = 3 Or y = 7
       xorValue = x = 3 Xor y = 7
       notValue = Not x = 3
       Console.WriteLine("x = 3 And y = 7. {0}", andValue)
       Console.WriteLine("x = 3 Or y = 7. {0}", orValue)
       Console.WriteLine("x = 3 Xor y = 7. {0}", xorValue)
       Console.WriteLine("Not x = 3. {0}", notValue)
    End Sub "Main
 End Module

x = 3 And y = 7. False
x = 3 Or y = 7. True
x = 3 Xor y = 7. True
Not x = 3. True

Power calculator

Option Strict On
 Imports System
 Module Module1
    Sub Main( )
       Dim value As Integer = 5
       Dim power As Integer = 4
       Console.WriteLine("{0} to the {1}th power is {2}", _
          value, power, value ^ power)
    End Sub
 End Module

5 to the 4th power is 625

    Sub Main()
        Dim A As Integer
        A = 0
        A += 10
        Console.WriteLine("A += 10 yields " & A)
        A -= 5
        Console.WriteLine("A -=5 yields " & A)
        A *= 3
        Console.WriteLine("A *= 3 yields " & A)
        A /= 5
        Console.WriteLine("A /= 5 yields " & A)
        A ^= 2
        Console.WriteLine("A = 2 yields " & A)
    End Sub
End Module

A += 10 yields 10
A -=5 yields 5
A *= 3 yields 15
A /= 5 yields 3
A ^= 2 yields 9
