Wouldn’t it be great if you could edit entries you make into the stock iOS Calculator app without having to clear them entirely? Fortunately, thanks to a little known trick that Apple has baked into its software, you can!
Simply swipe left or right across the Calculator display to remove entered digits one at a time.
This way, you won’t need to start all over if you hit a wrong button! Please note that this trick only works before you push the “=” sign.
Hopefully this trick will increase your productivity a little bit when using the stock Calculator on your iPhone or iPod Touch!
