vb.net

You are saying, you have done the coding for all buttons. first check are all buttons working properly. After that, coding for clear button, use that code Text1.Text=" ".
second step, you have to use some variables to retain the values of numbers.
Like Dim total1 As Integer
code for sum
Private Sub btnPlus_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles btnPlus.Click

total1 = total1 + Val(txtDisplay.Text)

txtDisplay.Clear()

you can do the same for minus sign.try that code. Hope it will be helpful for your calculator project

total1 = total1 + Val(txtDisplay.Text)

txtDisplay.Clear()

For clear text, use that code, txtDisplay.Text = ""

Hope it will be helpful for your calculator.
