Particular May Math SAT Problem

<p>The answer is none. </p>

<p>Zero is neither positive nor negative. Eleven zeros added together is zero, and none of them are positive.</p>

<p>it was 11 diff integers i think so you couldnt do all 0's</p>

<p>15, 0, -1, -2, -3, -4, -5 = 0;</p>

<p>1 positive number...</p>

<p>I thought that too, after I answered. I went back and checked. I think it just said eleven integers. </p>

<p>Anyone want to weigh in?</p>

<p>im pretty sure it said different integers, I put one</p>

<p>Guess I'll find out on the 30th. That sort of trickiness--whether I'm right or not--is right up CB's alley.</p>

<p>it said different. i thought the zeroes thing too, but it did say different. i remember very specifically looking back and noting it saying "different."</p>

<p>and to anyone who remembered me saying 1/y^2...sorry. i was all jumbled up. the answer was y^2...i actually did bubble that too (D), i was just confused, sorry.</p>

<p>The question <em>definitely</em> read "different" integers.</p>

<p>As for the angle bisectors question, I already put in a call to CB, and they should get back to me within a week to let me know if my challenge is valid. I <em>might</em> have misread the last statement in the question, but I highly doubt it since I re-read the question a few times and re-checked my work. If the question is indeed defective, they will have to throw it out completely, and score the test out of 53 questions instead.</p>

<p>regarding that math question....about the sum of 11 integers equaling 0...what is the least number of POSITIVE integers for this to occur...i'm quite sure the questions asked "what is the least number of POSITIVE integers..." thus...0 is neither pos/neg...so....yea...</p>

<p>tunit2190,</p>

<p>I think you misunderstood the question or the reasoning. The question specified 11 <em>different</em> integers that sum to 0. Let's assume the answer could be "zero positive integers." That means we would have to have 11 integers that are either zero or negative that somehow add up to 0. The only way that 11 non-positive numbers can add up to 0 is that all 11 numbers are exactly 0. But this cannot be true, since the question specified 11 <em>different</em> integers.</p>

<p>Then, we can see if we can have just one positive integer. This definitely works. Here's one example:</p>

<p>-9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 45</p>

<p>Therefore, the answer must be "one." By the way, when a question asks for the "least," the answer is usually not the smallest answer choice on a medium question and NEVER the smallest answer choice on a hard question (this question was medium/hard, but I forget the exact question number).</p>

<p>wow...thanks for the explanation!</p>
