                    You got the response you did because we don't do people's homework here. If you try to do your own homework, then we're happy to help with specifics.

                        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.
