<p>please post the weirdest/hardest math you have ever seen/solved…you know, getting a 800 in sat math also needs great luck along with skill.therefor,if u miss 1 que due to bad luck you are doomed.so please post ques so that we can get prepared for any problem</p>
<p>Gluttony</p>
<p>Well, this one isn’t necessarily weird or hard, but it does require thinking out of the box:</p>
<p>Blue Book, Practice Test 5, Section 3, # 17 (pg. 657)</p>
<p>If p, r, and s are 3 different prime numbers greater than 2, and</p>
<p>n=p x r x s</p>
<p>then how many positive factors, including 1 and n, does n have?</p>
<p>^answer is 8,i guess</p>
<p>pr, rs, ps, p, r, s, n, 1</p>
<p>thats 8 positive factors right</p>
<p>this is an interesting problem i encountered on my math 2c test:
ahhhh what is it…i forget
oh i remember</p>
<p>(note that the answer choices aren’t exactly the same, but the answer’s there)
for what value of n will n^99+2n^98 be a perfect square?
a.28
b.30
c.31
d.34
e.42</p>
<p>^Oh man, I remember that problem. The answer’s D.</p>
<p>And yeah, 8 is correct for the first one.</p>
<p>admonkey,is that a BB problem? test number and section please?</p>
<p>^ That’s not a BB problem, gluttony. It was off the June SAT Math Level 2 Subject Test, you won’t see anything like that on the SAT I Math.</p>
<p>no its not, i said its from my math 2c test.
its not released, at least i dont think so, its a question i remembered from my subject tests on june 08.</p>
<p>anyways, some other ones from my exams at school:
solve- (x+4)/(x+1)>(x+2)/(x+3)</p>
<p>actually, why am i even posting this, if you want the hardest/weirdest questions, go check out AMC and AIME.</p>
<p>^ what are AMC and AIME?</p>
<p>bb pg 738 #18 lol i got lost in the wording,but i think its really simple.
yet i dont understand XD</p>
<p>those are the math olympiad thingy; its like super hard math problems,but very interesting! =D
i agree u should check out artofproblemsolving . c o m
it has past amc problems, but those are really hard, they’re like college alg level, very interesting.
but u wont see them on SAT, so u can do those for fun,but not for sat =p</p>
<p>would it be a good idea to plug and chug for adamonkey’s 1st problem? whats the quickest way?</p>
<p>^ Plug and chug would overflow your calculator.</p>
<p>LOL If you wanna see actual tough questions go to [goIIT</a> - IIT JEE - AIEEE Entrance - online test series - online coaching - Engineering Entrance Experts - Education Forum](<a href=“http://www.goiit.com%5DgoIIT”>http://www.goiit.com)</p>
<p>yep artofproblemsolving too, and no, not all of them are college level 
For example, in india, you gotta solve most of such level questions in entrance exams to get into top univs like IIT (indian inst. of tech) :D</p>
<p>for what value of n will n^99+2n^98 be a perfect square?
a.28
b.30
c.31
d.34
e.42</p>
<p>n^99 + 2n^98 = n^98 (n + 2)
since n^98 is perfect square, we just require n+2 to be a perfect square too, so the answer is 34 as 34 + 2 is 36 which is a perfect square</p>
<p>see this [Maths</a> & Physics - Solved Questions](<a href=“http://mathplusphysics.blogspot.com%5DMaths”>http://mathplusphysics.blogspot.com)
Some of my solved questions, haven’t got time to update for some time now, will do it soon.</p>
<p>(x+4)/(x+1)>(x+2)/(x+3)</p>
<p>(x+4)(x+3) > (x+2)(x+1)
x^2 + 7x + 12 > x^2 + 3x + 2
7x + 12 > 3x + 2
4x > -10
x > -10/4</p>
<p>Ah spidey, now you understand why I’m so thankful that I moved from India. If I had to take such a beastly exam to try for admission to IIT (compounded by the rampant corruption in the admissions system in India), I would be so mad.</p>
<p>i wanted only SAT l QUESTIONS</p>
