我都是這樣計,但選擇題中只提供14, 2 ,-14 和 -2的選擇。我還想是我理解錯還是什麼?多謝你的解答。

我先翻譯一下題目:

Subtract -6 from the difference between the smallest and the greatest 2-digit prime numbers, what is the result?
把兩位數之中最大和最小的質數的差減以 -6,結果是多少?

The greatest 2-digit prime number is 97.
兩位數之中最大的質數是 97。

The smallest 2-digit prime number is 11.
兩位數之中最小的質數是 11。

The difference between the smallest and the greatest 2-digit prime numbers is
97 - 11 = 86.
兩位數之中最大和最小的質數的差是 97 - 11 = 86。

The result of the subtraction is
86 - (-6) = 86 + 6 = 92
