Simple calculator, simple problem...

[xxlethargyxx]

im trying to make a very siple calculator (to the point of only for lines of code) however the addtion dosnt work:

this is all my code:

Private Sub add_Click()
Text3.Text = Text1.Text + Text2.Text
End Sub

Private Sub divide_Click()
Text3.Text = Text1.Text / Text2.Text
End Sub

Private Sub multiply_Click()
Text3.Text = Text1.Text * Text2.Text
End Sub

Private Sub subtract_Click()
Text3.Text = Text1.Text - Text2.Text
End Sub

this is the code that isnt working even though it clearly should be:

Private Sub add_Click()
Text3.Text = Text1.Text + Text2.Text
End Sub

when i test it, i input 4 + 4 and it gives me an aswer such as 44.
why not eight? god visual basic is makeing me very angry!!!
