Of the five coordinates associated with points A, B, C, D, [#permalink]
 11 May 2008, 09:23
Of the five coordinates associated with points A, B, C, D, and E on the number line below, which has the greatest value? OA is A. But per the definition of absolute value, to me both A & E are correct answers. Am I missing something here? I finding it hard to believe that OG could have such questions.

Hi, If you look at the diagram carefully you will see that the arrow at E is slightly less that 2 , therefore E<2 while the arrow at A is exactly at -2. abs(-2) =2. The correct answer is A. Its just a trick Question to see how closely you read the question.

It's question# 20 in problem solving section, if anybody would like to take a look at OG's explanation.

Based on the attachment, E is just inside the 2 and A is right on -2. Answer: A.

But isn't absolute value always positive? Even if A was the farthest point, -2 becomes 2, correct?
