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的內置計算器是一個簡單易用的基本計算器，對于進行一些快速計算(例如計算餐館賬單上的小費)非常方便。 它對于更長，更復雜的計算也很有用。 但是，缺少一個按鈕。

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.

我們都熟悉鍵盤上的退格按鈕，無論是在移動設備還是計算機上，都可以刪除最后輸入的字符。 但是，計算器上沒有退格鍵。 如果輸入有誤，則必須刪除整個輸入并重新輸入。 不用擔心。 我們將向您展示解決該問題的簡單技巧。

Tap the “Calculator” icon on the Home screen.

點擊主屏幕上的“計算器”圖標。

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

在計算器中輸入一個多位數的數字。 要刪除輸入的最后一位數字，請在數字顯示區域向左或向右滑動。

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

輸入的最后一位數字被刪除。 每次滑動時，都會刪除一位數字。

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

此技巧也適用于科學計算器模式，可以通過將手機變為橫向模式進行訪問。

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.

要刪除整個當前條目，請點擊“ C”(清除)按鈕。 完成此操作后，它變成“ AC”按鈕，可讓您清除所有已完成的計算。
