hmmm... well... i have done the codings for each individual buttons. Eg for the button 9: Private Sub btn9_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn9.Click TextBox1.Text = 9 temp = 9 End Sub However, I can't figure out what should the code of '+' be. Since when a user clicks on it, he/she will select another number button. So is it simply this: TextBox1.Text = Int(TextBox1.Text) + Int(TextBox1.Text)

Here are some pointers: You need to hold some state somewhere. You also need to hold the fact that the user can type numbers like 98 (the code you showed does not append more digits, it replaces them). When a use clicks on an operator button (+-/*=) the program needs to store the current display, then it needs to accept a new number. When the user next pressed an operator it performs the function of the operator on the stored value and the current value. When a user clicks on a digit button it has to append the value on to the other digits received.

I have some idea for you: A. For the numeric buttons write scrip like this: private sub btn1_click(..) txtT.text = txtT.text & "1 end sub ' etc. for all numeric buttons B. For command buttons ( + - * / etc. ) write this script: private sub plus_click(..) Tmp1 = cint(txtT.text) act="plus" txtT.text="" end sub C. For = button write: private sub ans_click(..) Tmp2 = cint(txtT.text) select case act case "plus" : txtT.text = tmp1+tmp2 case "minus" : txtT.text = tmp1-tmp2 .... end select end sub This code handle only one action per two numbers. If you wans to handle lot of actions, like windows calculator, you need to add a boolean trigger that will be True if one action had been chosen and when the user select another action it will do the action selected before, then put the result in Tmp1 and then reset the trigger to False. This process will continue until the user click the = button. I'll don't give the answer for this so quickly .. ;) I give you time to think about it.
