How to delay button commands.. One click = one command at a time.

[Reapism]

   Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Button1.Text = "1"
        Button1.Text = "+"
        Button1.Text = "2"
        Button1.Text = "="
        Button1.Text = "3"

Essentially making it 5 buttons clicks to reach "3"

Problem: Runs all commands and ends up at 3.

Additional information:
I was informed by my programming teacher that adding a loop should do it but I am not entirely sure... If so, How do I do it?
