[RESOLVED] Understanding XOR

[Liquid Metal]

I am trying to understand how XOR works. Why is this equal to 25?

    MsgBox 77 Xor 84

Just testing this:

Public Sub Main()
    Dim intFix As Integer
    intFix = Fix(256 * Rnd)
    Range("A1").Value = intFix
    
    Dim intAsc As Integer
    intAsc = Asc(Mid$("Test", 1, 1))
    Range("A2").Value = intAsc
    
    Range("A3").Value = intFix Xor intAsc
    
    MsgBox 77 Xor 84
End Sub
