我已經寫出1～0的數字鍵，清除（C），負號，等於
但是-*/都不動耶？
這是我的程式碼：

Private Sub Button13_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button13.Click
TextBox1.Text = TextBox1.Text & "+"
End Sub

Private Sub Button14_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button14.Click
TextBox1.Text = TextBox1.Text & "-"
End Sub

Private Sub Button15_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button15.Click
TextBox1.Text = TextBox1.Text & "*"
End Sub

Private Sub Button16_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button16.Click
TextBox1.Text = TextBox1.Text & "/"
End Sub

Private Sub Button17_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button17.Click
Dim myArray() As String = Split(TextBox1.Text, "+")
Dim Total As Single

Total = 0

For i = 0 To UBound(myArray)
Total = Total + Val(myArray(i))
Next

TextBox1.Text = Total
End Sub

這樣為什麼減乘除會沒辦法用？
