Did you try to publish the test, not only sharing it privately?

That is it – hopefully ;-)
Most of the courses in German universities are held in the German language, burt there are quite a few universities that provide courses in the English language. There are even quite a few universities that do ALL their teaching and coaching in English, here you have to mention especially the so called “international universities” that provide international MBA-studies.
You showed me what to look for – after that it was simple.
Here is the math behind that wonderful trick:
(10x + y)(10x + 10 – y)=100x2 +100x – 10xy +10xy +10y -y2 = 100x2 +100x + 10y – y2 = 10x * 10(x+1) + (10-y) * y
Looking forward to seeing your way of doing this!

have a look at this picture – it will explain the idea. The semicircle lies axially symmetrical to one diagonal of the square. From this follows that the length of the square has to be x + x/sqrt(2). With a given length a you now can rather easily figure out x.
You only need seconds if you use and automate the use of the binomic formulas:
(x-y)(x+y) = x2 – y2 and (x+y)2 = x2 + 2xy + y2
then, e.g. : 83 * 87 = (85-2)(85+2) = (80+5)2 – 22 = (6400+800+25) – 4 = 7221
automated: take the square of the tens, add 10 time the tens, add 25, subtract the square of difference to the number with the ending five (i.e. 85-83=2), voila.
sir, one should need more than 5 seconds to calculate by the method you stated. a good X th standard student in India knows this trick. But, i have a trick by which it really takes less than a second to do it! These are some special tricks which you will learn in the subject VEDIC MATHS FOUND in vedas. I’ll tell about vedas afterwards.
I’m posting this trick separately in this discussion.
89=72 & 37=27 THEREFORE 7227
pls solve 59 multiply by 56 through ur trick
Be x the radius of the maximal semicircle and be a the length of the square (=1 for the unit square), then x + x/sqrt(2) = a
So for the unit square:
x = sqrt(2)/(1+sqrt(2)) —> the area of the semicircle of the unit square equals 0.539 square units
Dear sir, if x is the radius then how can be the area is x+x/sqrt2. Since x i.e.radius has dimensions of length how can be x+x/sqrt2 is area. It also has dimensions of a length, while dimensions of area are length^2.
By the way how did you find x?........Plese reply.
As nearly always: It depends …
It depends on the meaning of “good-looking”. Beauty lies in the eye of the beholder, as you know. You can’t actually reduce “good-looking” just to physical appearance, the overall impression always integrates the physical appearance with social skills, with “how good you get along with one another” etc.
We know from research that the first 30 seconds of a first meeting count the most – the word of the “first impression” is more than right here!
So, if we generalize “good-looking” to “making a good first impression” (with “the look” being a great part of that!) – then yes, good-looking people get a better start!
You may ponder the question if what is true in relationships between guys and girls perhaps doesn’t count in business-relationships. Aren’t we supposed to listen to reason when it comes to business-relationships?
I don’t really think so. In the end we are all human, so if there are no preeminent reasons against the better looking person he/she will get the job.
That said, nobody who got (and kept!) a decent job should be blamed for “getting that job only because of his/her physical assets” – in the long run other personal, social and professional qualities outweigh the looks!
If you love Raymond Chandler, what about Dashiell Hammett? – For me he is the king – black, realistic and dry to the bone…
Hi Alexandro,
just keep patient ;-)
The error-message you get is only a very misleading information that the presentation you uploaded isnt rendered yet. Just wait for a few minutes and everything will work smoothly. I uploaded your ppt to learnhub myself and it works wonderfully (after about five minutes wait-time)

Adam, that is a great lesson!
For those out there who are deeply interested in available light photography, let me add two ideas I sometimes use to get the best out of my pictures in low-light situations:
Sorry, Adam, that is a misunderstanding, I wasn’t thinking of the meeting of Snape with the Potter-sisters, that is indeed a memory out of the pensieve, i was thinking about the meeting of Snape with Narcissa and her sister when he vows to help her son.
Ah your right! That was a pretty rare case… if not the only time that ever happened. I still have to say killing off Harry Potter would have to end the book. I couldn’t see it being from any other perspective aside from MAYBE Voldemort’s.
There are parts of the books not written in Harrys perspective, e.g. the meeting of Snape with the two sisters, so Oren may have a point here.
@Oren: As I said, I cant see any hint in the book that Dumbledore was gay…
To the ending: I don’t know if I remember correctly (it is some time ago I read the book) wasn’t it that Harry didn’t kill Voldemort, but Voldemort did so himself?
I agree with you in that point that normally happy endings are boring and often diminuishing the preceding story – but it wasn’t that way in this book (only my opinion).
@Oren: I agree with Adam – I was really content with the overall ending of the Harry Potter series. The book would be even better without the last part with the grown up Potters – as it is my belief that a writer should write til the end of a novel but then stop immediately ;-)
I really was impressed by the dying and surviving of Harry Potter. – For me this has nothing to do with Christianity, it was simply a very logical construction over all the seven books, very deep and without a flaw – that’s what impressed me. I now believe Rowlings telling she wrote the end first.
@Malgosia: I wouldn’t mind Dumbledore being gay, but I can’t read that in the book. Dumbledores friendship with Grindelwald shows all signs of the connection of two boys with extraordinary minds, bound together by thirst for knowledge, young ambition and juvenile arrogance – but I cant find any explicit homosexual annotations.

WHAT WOULD FOREIGN STUDENTS DO IF THEY DONT KNOW GERMAN ..IF THEY WANT TO STUDY IN GERMANY .
