How do i put number buttons for calculator?

[Deep2]

Here's what i have so far.

Private Sub Add_Click()
TextBox3.Text = Val(Value1Text.Text) + Val(TextBox2.Text)
MSD.Text = "+"
End Sub

Private Sub Clear_Click()
TextBox3.Text = 2
TextBox2.Text = 1
Value1Text.Text = 1
MSD.Text = ""
End Sub

Private Sub Divide_Click()
TextBox3.Text = Val(Value1Text.Text) / Val(TextBox2.Text)
MSD.Text = "/"
End Sub

Private Sub Exxit_Click()
Unload Me
MsgBox "You Have exited out of Calculator"
End Sub

Private Sub Multiply_Click()
TextBox3.Text = Val(Value1Text.Text) * Val(TextBox2.Text)
MSD.Text = "*"
End Sub

Private Sub Square_Click()
TextBox3.Text = Val(Value1Text.Text) ^ Val(TextBox2.Text)
MSD.Text = "^"
End Sub

Private Sub Subtract_Click()
TextBox3.Text = Val(Value1Text.Text) - Val(TextBox2.Text)
MSD.Text = "-"
End Sub

How would i go about making buttons like, 1, 2, 3, type buttons? It's kind of confusing for me.
And if it helps i'm trying to make a calculator and i started 2 days ago.
