А вы его училки не пробовали задать задачки Mathemat-а ? Я, было дело, над препедавателями физики и химии так подкалывался :)


Since my time, 'they' have changed some definitions

The wording of the simplest tasks can be ambiguous

Typography is printers' faults are common.

From the proposed 4 answers to choose one, but it's not there

but there's an option from the previous assignment.

I dread to think what will happen next

Гы... Погоди, ты еще не знаешь, что такое сольфеджио во втором классе музыкалки! Чистая квинта!


He's a techie, he's not going to music and he's overloaded anyway.
 

Mischek, in the sense of a techno-techno-junior - he's a tehanalyst :) But seriously, I, for example, now I really wish I had started at the age of 6 or 7

all this stuff. Who knew then that things would turn in the direction of "market profile". The main thing is not to miss out on the years.

Оригинальное :) . Спасибо за задачу, как все просто то...

Yes, it's pretty straightforward. My first answer was wrong.

 

ANSWER to problem #6, about the nut:

-

How could a metal nut float on water and jump out of a bucket? Everyone thought the nut was made of steel, but I didn't write that.

The nut is made of potassium. And how it happens is clearly seen in this video: https://www.youtube.com/watch?v=6kVOyqyt5UI

Unfortunately there is no video of the 100g piece, but the effect is much better there. I wouldn't advise repeating it - it's very dangerous.
