How to add values in a1,a2 and a3 cells and to show the result in a4 only by
clicking a command button inserted from the tools box. I want the simple
codes step by step.

In design mode, double-click on the button, and in the window that appears, put the code

Private Sub CommandButton1_Click() ' This may have number other than 1 appended
Range("A4").Value = Application.Sum(Range("A1:A3"))
End Sub
