I think I might have a solution for you.  You can use calc.exe and parse keystrokes to it, then one the equation is finished you just get your script to copy (ctrl+v) and you can the read the last entry in the clipboard.  Read the help file to get the keyboard shortcuts like 'y' for to the power.  It might not be a very nice way of going about this but if anyone else has a better suggestion about doing this have a go at it.
