TextBox3.Text = a + b

End If

Private Sub cmdminus_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdminus.Click

Dim a As Integer

Dim b As Integer

a = TextBox1.Text

b = TextBox2.Text

TextBox3.Text = a - b

End If

Private Sub cmdmultiple_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdmultiple.Click

Dim a As Integer

Dim b As Integer

a = TextBox1.Text

b = TextBox2.Text

TextBox3.Text = a * b

End If

Private Sub cmddivide_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmddivide.Click
