i want to know about how to manipulation textbox to produce an arithmetic result

[kpomeru]

ok lets say i have three buttons,
button1.text = "+"
button2.text = "9"
button3.text = "="
and a textbox.text = "0"

if i click any of first two buttons, the .text value adds to textbox1.text

say(0+9+9+9)

how do i write my code under button3 that my result will output 27 on the textbox

Im gonna get told off again, but heres a very crude solution:

Dim v As New DataTable
TextBox1.Text = v.Compute(TextBox1.Text, "")

please note, this doesnt really do complicated sum's well, rather just basic maths.
