It's common to make mistakes when typing numbers into your iPhone's calculator. Since the app doesn't have a backspace, you're likely to find yourself deleting everything and starting over. The good news is that there's a way to delete individual digits instead of removing the entire number. Here's how you can use the feature:
- Open the calculator app on your iPhone.
- Enter a number.
- Swipe left or right over the number you just entered.
- Each scan will delete one digit.
If you are having trouble with the function, make sure you are scanning the numbers displayed at the top of the screen and not the numbers on the calculator. If you are doing a calculation and make a mistake with a number, you can press the C (Clear) button to clear only your current entry. The AC (All Clear) button resets all previous steps in the calculation. Therefore, press it only if you want to start over.

On the other hand, the iPad still doesn't have a calculator app, and it doesn't look like Apple plans to add one anytime soon.
