Hey guys, I'm pretty bored and figured I'de make a calculator for my homework and everything. Well I've got subtraction, division, multiplication , etc working, but when I do add it adds the numbers togethor

so, If I add 5 + 4 it equals 54.
If I add 7+2 it equals 72. Everything else works fine. Can anyone tell me what I'm doing wrong?

Code:
If addbutton Then
equalbox.Text = onebox.Text + twobox.Text
End If
