I've lost the piece of paper I scribbled it on but this is a translation (from memory) of part of my final Indonesian exam:

Indonesian Exam wrote:I bought my digital camera for sex documentaries for school work

I was quite disturbed. Didn't even get to share with anyone cause I was the only one doing the exam.

The phrase "train wreck" has gotten a little play in both my exams so far - first when it took me about half an hour to correctly cube a 3x3 matrix, then when I got about two thirds of the way through a long question only to realise that the final part needed something I had completely forgotten to revise... I think next time I need to use it I'll draw a little picture of Thomas the Tank Engine on his side, wheels spinning. (So far things have gone OK, though.)

Not math, but my class enjoyed it.

In my German 3 class a few years back, we were taking a listening comprehension test, multiple choice style. The question (in English, for your reading pleasure) was:

What are you repairing?
A) Your horse
B) Your life
C) Your bicycle

Whenever one of my former classmates is having a bad time, the phrase 'Was reparierst du? B.' usually suffices to this day.

The lecturer told us that if we were a borderline fail, and we produced something like this, he would pass us.

In the school I went to, there used to be a math camp, for preparation of math olympiads. Quite a lot of folks there, and on the first day there would be a math contest, a sort of olympiad that you solved in teams. Not really hard, but the more difficult problems were at the end. So, as our team got the problems, the last problem was:
13. Prove that for any natural number n >2, there do not exist such natural numbers a, b and c such that a^n + b^n = c^n.(12 points)
After asking the one who had chosen the problems WTF? and writing that we do in fact have a solution but it doesn't fit in the margins, we continued with other problems. Later we learned, though, that some team had answered somehow like this:
"Banal. Substituting the powers with the middle elements of the Ivanovsky equation, the problem simplifies into a trivial one."
Afterwards they also produced the Ivanovsky equation which was, in essence, a whole lot of mathematical symbols heaped together without any meaning. (or that's what we thought)
After that, I wanted to be the one who organizes the thing since I wanted to propose the trisection of an arbitrary angle as a similar problem. (since everyone knows that it can't be done, while, actually, it can) Alas, it was then too late for me.

By leaving out or weakening the "with a straight edge and compass" restriction, right?

This isn't really maths, I suppose, but it's from a maths with computer science paper so I might as well post it. It was part of an Operating Systems question - most of the question was about the CPU scheduling algorithms in Windows NT and Unix, then the last part was essentially "speculate wildly about CPU scheduling in massively parallel computing". My answer included the phrase "causing CPU utilisation to plummet like a sheep. (Ni!)" So I was low on sleep... :-) The exam went well overall though.

To be explicit, you need to say "unmarked straight edge". You can trisect an angle if your ruler has two tick marks on it.

It is also possible by using origami - in which case you don't even need a compass or a straightedge - if the angle provided is on a piece of paper.

During today's English exam, we had to write sentences showing that we knew how to use the words properly. By the last one, I was bored so I wrote "Look, I'm tired of writing sentences. Here's a hint for what wrangle means: it has to do with rope and knots. Are you happy now?"

My friend also managed to include the words "40 cakes" in all of his 10 sentences. The sentences would be things like "The cashier cowered behind the counter as Lex Luther stole 40 cakes. 40 cakes. That's as many as four tens. And that's terrible."

This sound interesting, but I can't see how it works, I take it the method is not trivial. What are the permitted operations for applying origami to geometry? (don't tell me the answer I want to work it out)

PS. If you start with a piece of paper with curvature not-equal-to-zero can you do non-euclidean geometry?

Most of them are pretty obvious:

-given two points, you can fold one point onto the other;
-given two points, fold a line through both points;
-given two lines, fold one onto the other;
etc.

The one that's particularly important for trisecting an angle is
Spoiler:
given two points and two lines, fold one point onto one line and the other point onto the other line (with a single fold).

Our Maths teacher is giving up on us. All but about 7 (out of 24) failed her class. Luckily I'm among those 7 :D

I just remembered one from a test I took several years ago in a science class.

Now, if I remember correctly the first couple questions (around 20 or so) were one-word answers, and the last few asked for a couple sentences. But, for some odd reason, there was a gap between the last one-word answer blank and the first short-answer field. So our answer sheet looked something like this:

Code: Select all

17. _______________  18. _______________

19. _______________  20. _______________


21.

It was also a pretty easy test, so I finished early and became bored. So I added a blank numbered 20½ and wrote in something silly (forgot what exactly). When I got it back, my teacher had put a slash mark through #20½ and written "[imath]-\frac{i}{\pi}[/imath]" by it.

Yup, he took off an imaginary number of points for it. :lol:

Interestingly, this was part of the power question from ARML 2006. I think my team got this right...

And this is more a stupid question than answer, but here it is.
On one of my dad's questions in general biology when he was an undergrad, the teacher had the following question:

Which of the following lay(s) eggs?
a. All birds
b. Most reptiles
c. Some mammals
d. A and b
e. All of the above

Spoiler:
The answer is of course d (a and b), because it's not some mammals that lay eggs, it's only a few. And the lecturer didn't intend it to be confusing - that was his honest answer.

I lost 18 points for that in a linear algebra homework page. in a question that was worth about that much. I also lost 5 points for writing(n+1)C2 instead of n(n+1)/2, and 15 for saying the third line was linearly dependent on the other two and therefore the rank of the matrix was smaller then 3. that got me the comment "you have to check all the 3*3 minors." what the hell?

I remember in Year 10, I was dropping geography and hence decided to have fun in my end of year exam since it didn't really matter. Saying the location of the Earth's crust was at PIzza Hut was an example, in addition to replying something along the lines that "Mao is an evil totalitarian dictator" and "Because they can ask futile demographic questions in Geography Exams" to the Question "Why would China keep population records? [2 reasons]." The essay question was especially fun to do but I daresay Aristotle was was right when he said "wit is educated insolence," because that's the word my teacher used to describe my exam when she put me in detention for it.

Completely worth it though.

This doesn't have anything to do with maths, chemistry or philosophy in the slightest, but it's relevant not only to this post but XKCD in general. Me and my friend work in a cinema, and we recently took part in the annual employee film quiz thing. For every question that we didn't know we just put "sudo Kevin Bacon".

It didn't work, unfortunately.

While you did write out an appropriate question, you did not answer that question completely (you only did one part of it).
