Quiz: Could You Pass Eighth Grade Math?

14/16

Not bad for doing it at nearly 3am and not really paying attention.

Funny thing is, I hate math!

Edit: and I'll be 22 on Thursday so needless to say I've been out of 8th grade for a while.

I guess I can't pass eighth grade math. I got about three problems down, and didn't have any problems doing them, but I got so bored with math that I stopped taking the test.

So who can give the surface volume of a tesseract (4D cube) of those dimensions? Hypervolume?

Hooked on Math didn't work for me I guess

A tesseract?? Geez, haven't seen that word since reading "A Wrinkle in Time". But I am most definately positive that the volume isn't 0.

16/16 it appears.

You clearly have a handle on what the Illinois State Board of Education thinks an 8th-grader should know.You got 15/16 correct.
I got the one with the flower pot wrong. Still, I'm pretty damn please with myself, since it's been...*calculates in head*...twelve years since I was in eighth grade.

Bah, I got 16 out of 16 correct!

Crap, missed the last one, forgot to subtract sum of legs from hypotenuse. And I'm in tenth grade.

Bah, says you? How long have you been out of eighth grade, eh? Eh?

16/16

Tried like hell to do the last problem in me noggin, but it would appear that my brain draws the line at square roots at around 15^2.

Wasn't someone giving out kisses?

Edited to note that I done got out of 8th grade ~17 years ago. Me go laugh/cry now.

Like some others here I haven't touched math in a long time, the last math course I took was introductory calculus in first year university. The most involved math I've done lately is calculating all the stuff for my income tax returns, and like my BF I'd be hard pressed to remember anything like derivatives & such.

Wait, what?

16/16 when I took it, no calculator. I wonder if they meant for it to be taken with a calculator, figuring out sqrt 520,000's kind of a pain. Really it's figuring a good approximation for sqrt 13 that gets yah though.

One quibble with the test is that I really don't see what the first question (the pathfinding/arrows question) has to do with mathematical skill. It's easy enough that I'm sure everyone gets it, but I just don't see its relevance.

i got that one wrong

even more embarassing, 4/16. I work in IT, i don't need maths! :hmmmph:

Hey, i know my 2^X, and aspect ratios...

Well, 16/16. I found this test much easier than the one I did in the real school two hours ago. That one took 3 hours to finish, whew...
I'm not too familiar with the American school system; how old are you when you're in the 8th grade?

For a cube with side 'd', the hypervolume is simply d^4.

Projecting a cube into 4D, would create 24 surfaces (6 surfaces on cube + 6 on projected cube, +12 connecting surfaces, one for each edge), so 24d^2.

A 4D cube sure looks messy on a 2D piece of paper....

Doh! 14. I always did make stupid mistakes in exams...

Um, how old's an eighth grader?

16/16.
Multiple choice math tests? WTF?

Ted · Post by **Ted** » 2003-05-21 12:15pm

16/16, all in head.

I'll admit that the cube was an "educated guess".

Even better seeing as I only did 2 months of grade 8, yet still passed.

I thought that was odd, too. We got a few problems like that in AS Discrete Maths, but there you were marked as much for method as for the answer (there's an algorithm you can apply to the network). But it seems wasted on a multiple choice paper.

8th grade is about 13 yrs. of age.

*raises hand* Err...Permutations or Combinations, Darth Wong?

I dunno. There are too many variables for that, although statistics were never my thing. (Which is why I'm taking AP Calculus, even though AP Stat is supposedly a joke course)

I think Cmdrtsweevo has already hit it about the network algorithm.
