Comment From Craig Finseth:
You can use INPUT and SWAP to keep two complete calculations going at once. Do the first one, press INPUT, then do your second one. Do SWAP to switch back and forth. Make sure that you have completed any pending operations first. Pressing C or turning the calculator off/on clears both.
