Dim s As String = "0123456789<>+-*/"

Dim zf108 As String = ""

Dim Val3 As Integer

For i As Integer = 1 To 108

Val3 = Rand.Next(0,15)

zf108 = zf108 & s.Chars(val3)

Output.Show(zf108)

Dim s As String = "0123456789<>+-*/"

Dim zf108 As String = Rand.Next(0,9)

Dim Val3 As Integer

For i As Integer = 1 To 107

Val3 = Rand.Next(0,15)

zf108 = zf108 & s.Chars(val3)

Output.Show(zf108)
