I'll tell you how to make one that just adds and subtracts

1) Make 13 buttons [0-9 and +,- and =]

2) Make a text box [call it txtOperation]

3) Under the code for Button1_Click, go to the end where it says handles. Add every buttons name (except =) plus .click, separate each button by commas.
[...Handles Button1.Click, Button2.Click....etc]

4) Declare a global variable strOperation

5) Use this code under Button1_Click

Dim clicker as Button

clicker=CType(sender,button) 'this will be able to tell which button you pressed

strOperation=strOperation+clicker.Text

txtOperation.Text=strOperation

6) Use this code under btnEquals_Click

intResult=Convert.ToInt32(strOperation)

txtOperation.Text=intResult.ToString



I hope this helped you,
Jordan
