AMC8 1992 · Q3. It mainly tests Arithmetic misc.

What is the largest difference that can be formed by subtracting two numbers chosen from the set \{-16, -4, 0, 2, 4, 12\}

从集合 \{-16, -4, 0, 2, 4, 12\} 中选择两个数相减，能形成的最大的差是多少？

(A) 10 10

(B) 12 12

(D) 28 28

(E) 48 48

Answer

Correct choice: (D)

正确答案：（D）

Solution

Answer (D): to obtain the largest difference, subtract the smallest number, −16, from the largest number, 12. Thus 12 − (−16) = 28.

答案 (D)：要得到最大差值，从最大数12减去最小数−16。这样12 − (−16) = 28。
