you'll have to split the string first using some form of delimiter (an operator perhaps), parse them, perform the calculation and then return the result.

Try to split the text then call divide function. Dim num() As String = txtInput.Text.Split(CChar(vbTab)) '//Throw number to function Divide(num(0), num(1)) Hope this help. :)
