Official SAT March 10 Math Discussion

<p>^^ i put that</p>

<p>was it an empty set?</p>

<p>Zero is even... I learned that in Algebra II. I'm pretty sure... unless my teacher taught us something that wasn't true <em>gasp</em></p>

<p>thanks aquamarine and cocnutblue!</p>

<p>chinnu: It could not be an empty set beacuse it said the UNION, if it had said intersection, then yes it would be empty, sorry bro</p>

<p>Doesn't union mean the combination of both sets... so why is it empty set?</p>

<p>For those of you who had the experimental in the math section... which one was the experimental? I had two math sections in a row, im hoping that it was the first of those two... i think section 6 or 7... Was it the one that asked, for the last question: There are 3 points, which of the following CANNOT be true : AB+AC>BA (this might not have been a choice, just showing that these are what the answers looked like).</p>

<p>Oh, and was 4/15 (A) an answer? or was that in the experimental section... I can't remember</p>

<p>matt i had experimental in math
and i had that AB CA thing
does that mean that is the
experimental section?</p>

<p>matt:</p>

<p>I did not get the 3 points question so I'm guessing that was your exp section</p>

<p>aquamarinne: 4/15 was the answer</p>

<p>Oh, and was 4/15 (A) an answer? or was that in the experimental section... I can't remember</p>

<p>yes, 4/15, and it wasn't experimental, i had that Q and i didn't have experimental math.</p>

<p>I hear the experimental math had lots of probability and combination Q's, including one about desk arrangements...</p>

<p>for the union one i put (1,2,3,4) is that right?
bc zero is neither even nor odd right?</p>

<p>yess i had the desk arrangement one
i had nooo idea what it was</p>

<p>Hahaha. I got pwned by the experimental. I repeat: it better be experimental or else I will have a horrendous math score.</p>

<p>for the union one i put (1,2,3,4) is that right?
bc zero is neither even nor odd right?</p>

<p>yes, thats the right answer, but your reasoning is a little off. zero is even, but it's not POSITIVE :)</p>

<p>How the heck is zero an even number? that's ridiculous.</p>

<p>How the heck is zero an even number? that's ridiculous.</p>

<p>because it's of the form 2x .. x = 0 :P. odd would be 2x+1</p>

<p>and mainly it's a convention thing. just like 1 not being a prime and 0! = 1..</p>

<p>i got screwed over during math. my contact seriously starting falling off my eye and i had to cover my eye and read everything with like one eyeball the entire time. it sucked. </p>

<p>but is the answer the 1,2,3,4 one</p>

<p>i always thought 1 was a prime and 2 wasnt, but this weekend while i was doing a practice test i understood =)</p>

<p>okay so zero is even but not positive. thanks! math is looking a bit brighter for me</p>

<p>omgosh for the {0,1,2,3,4} question... did it say that the even/odd numbers were POSITIVE?!?!</p>

<p>cas if it did... crap.</p>

<p>omgosh for the {0,1,2,3,4} question... did it say that the even/odd numbers were POSITIVE?!?!</p>

<p>cas if it did... crap.</p>

<p>yup, sorry :(</p>

<p>wait... was the answer for the chinese daughter story unconcern or ambivalence??</p>

<p>because the meanings are like the same!</p>
