If you have numbers from other applications to calculate, tap and hold the screen until the Formatting tab appears. Launch the iPhone calculator and tap and hold the space that shows the entered numbers. When the Formatting tab appears, you tap Tap. Similarly, if you want to use numbers in another application, tap the numbers in your final answer and copy them to the Format tab.

Consider How You Use the Buttons.

When using a calculator, many of you will enter a number, hit a symbol, type a few more numbers, and hit another symbol. But that is not the only way it can be done. Let’s say you want to convert to% decimal form. Normally, you type the number and press the% key. However, you can first tap and hold the% key, then type in the number and let the% key get the same result. Try it with other buttons and symbols, sometimes you will find it faster.
Make Your iPhone Speak the Numbers.

If you want to know how the number speaks, you can call it your iPhone. In the iPhone calculator app, you can tap and hold the current number, or double-tap it, then select “Speak”.iPhone
Change the Calculator’s Color.

There aren’t many ways to change the colors on a calculator, but that means it can’t be done. The Dark Wall and later calculator in iOS 13 already has a dark theme so it doesn’t matter, it does nothing to the Smart Invert theme. However, you can use classic invert and color filters to see how you want it. For Classic Invert, in the “Accessibility” preferences.
