Javascript has variables, no? You can use them to maintain the state of your calculator app.

There are numerous ways you can do it. You can have one variable specifically for the previous value. So just before you assign a new value to the textbox, assign the current value that is in the textbox to your history variable, then insert the new value into the textbox. You can even do this in an array and store the, say previous 20 values in an array.
