iPhone users, turns out you've been using your calculators wrong. It might be one of the most used apps, but there are so many features in it that are still unknown to the users. Read on to find out how you can use your app efficiently and to its best capability.

Unknown Features

The first thing to know is that you can actually delete individual numbers by swiping across the display. Meaning if you write a "2" instead of a "1," you don’t have to end up erasing the entire calculation to fix it. You can also save some time while doing calculations with a handy trick. If you’re planning to go to another app, you can actually copy your calculator results without actually going back to the app! For this, tap the app, hold down, and you’ll get an icon to let you copy your recently done calculations! Who said that the calculator could only let you do simple math sums?

Scientific Calculator

One of the other biggest uses of the iPhone calculator app is its ability to be used as a scientific calculator too, instead of just a normal one. For this, all you have to do is turn your phone horizontally and watch as it magically switches from a simple tool to a more complex one. Ensure that your screen lock isn't on for this to work. With this calculator, you can perform high-functioning calculations. You can even switch from scientific to normal and back easily without actually losing any of your calculations. Just turn your phone sideways as per your choice! Isn’t that cool? An added bonus is that the scientific calculator also has some hidden features! You can reveal some hidden features of this version by just tapping on the button marked 2nd on the app, and you’ll be able to see some new and hidden functions.
