iOS’ built-in calculator is a basic, simple-to-use calculator that’s very handy for doing some quick calculations, such as calculating the tip on your restaurant bill. It’s also useful for longer, more complicated calculations. However, there is one button missing.

iOS的内置计算器是一个简单易用的基本计算器，对于进行一些快速计算(例如计算餐馆账单上的小费)非常方便。它对于更长，更复杂的计算也很有用。但是，缺少一个按钮。

We’re all familiar with the backspace button on a keyboard, whether it be on a mobile device or a computer, that allows you to delete the last character you typed. However, there is no backspace button on the calculator. If you make a mistake in an entry, you have to delete the whole entry and re-enter it. No worries, though. We’ll show you a simple trick that solves that problem.

我们都熟悉键盘上的退格按钮，无论是在移动设备还是计算机上，都可以删除最后输入的字符。但是，计算器上没有退格键。如果输入有误，则必须删除整个输入并重新输入。不用担心。我们将向您展示解决该问题的简单技巧。

Tap the “Calculator” icon on the Home screen.

点击主屏幕上的“计算器”图标。

Enter a multi-digit number into the calculator. To delete the last digit entered, swipe either left or right on the number display area.

在计算器中输入一个多位数的数字。要删除输入的最后一位数字，请在数字显示区域向左或向右滑动。

The last digit entered is deleted. Each time you swipe, one digit is deleted.

输入的最后一位数字被删除。每次滑动时，都会删除一位数字。

This trick works in the scientific calculator mode, as well, which can be accessed by turning your phone into landscape mode.

此技巧也适用于科学计算器模式，可以通过将手机变为横向模式进行访问。

To delete the whole current entry, tap the “C” (clear) button. Once you do that, it turns into the “AC” button, which allows you to clear all the calculations you’ve done.

要删除整个当前条目，请点击“ C”(清除)按钮。完成此操作后，它变成“ AC”按钮，可让您清除所有已完成的计算。
